ecostat2 and Irus products

A quick checklist of mistakes to avoid.

• The ‘one size fits all’ heater specification
Student accommodation comes in all shapes and sizes and it is important to specify the correct size heater in each and every room.

Each room will have different criteria for heat loss to be calculated accurately. Size of room; position; number of outside walls; whether the room is on the ground, middle or top floor; size and positioning of windows; glazing type; door size; whether there is heating in the corridor; insulation specification. All of these, and other factors, need to be taken in to account to ensure the correct heater output is specified.

• Placing the thermostat or control unit too close to the heater.
If the thermostat is positioned too close to the heater it will register a high temperature too quickly. It will then cut the heat before the rest of the room has had chance to warm up. The result will be that rooms will never reach the desired setback temperature and the energy saving programming will not operate.

• Placement of heater and control unit in confined area.
In a lot of student accommodation the entrance is often narrower than the body of the room, usually because there is a toilet/shower room by the doorway. It is not advisable to fit both the controller and the heater in this area. This is because the circulating warm air will heat this area up more quickly than the rest of the room. The thermostat will turn the heater off before the rest of the room has reached the setback temperature. If the thermostat is positioned in this area we recommend the heater is positioned in the main part of the room and that way the room will heat up before the thermostat registers the setback temperature. If a PIR sensor is integrated into the controller (ecostat2: PRE5203EC2 and PRE5204EC2 – Irus: PRE2000CU3) the unit should be mounted as centrally in the room as possible so that it can detect movement in as wide an area as possible.

• Positioning of the thermostat over a heat generating electrical appliance.
Mount the thermostat as far from electrical appliance as possible. If it is close to a television, fridge, cooker, hob, desktop computer or other electrical device that generates heat, it will not be able to read the temperature of the room accurately.

• Positioning the thermosatat next to a window.
If mounted next to a window the thermostat will not be able to measure temperature accurately as the flow of thermals near a window is not indicative of the the rest of the room space.

• Coat hooks above a thermostat.
If coats or anything else covers the thermostat it will not be able to read the temperature of the room and therefore will not control the heater effectively.

• Boxes and other paraphernalia obstructing the heater.
Anything placed in front of the heater will inhibit its performance in circulating warm air. Electric heaters reach high temperatures and any obstructions can be present a potential fire hazard.

• Curtains and other obstructions
Mounting the thermostat behind curtains or other obstructions will result in inaccurate temperature readings.

• Mounted close to forced heating or ventilation systems.
Mounting the thermostat close to air vents for heating or cooling will result in inaccurate temperature readings.

• The controller can not ‘see’ the room.
If the unit is fitted with a PIR sensor (ecostat2: PRE5203EC2 and PRE5204EC2 – Irus: PRE2000CU3) the unit must have a lear view of the room so that it can detect movement. Therefore it should be mounted as centrally in the room as is practical and at a height of between 1200mm and 1400mm from finished floor level.

 Installation of ecostat2

WITH ELECTRIC HEATERS AND WET HEATING SYSTEMS

    • All installation and wiring works must be completed by a competent person and conform to relevant regulations in force at time of installation.
    • Locate the thermostat at least 300mm away from the nearest edge of the heater. Ensure the thermostat is placed where it cannot be affected by extraneous heat sources, for example: televisions, desktop computers, fridges. If fitted too close to an extraneous heat source the thermostat will not function correctly. Do not mount the thermostat above a heater or radiator. Mount the thermostat at the centre point of the room if possible. Do not mount the thermostat behind curtains or room dividers.
    • Ensure the thermostat has a local means of safe isolation. A double pole isolator must be used. A PRE6000 double pole key switch is recommended.
    • Mount the thermostat between 1.2m and 1.4m from finished floor level.
    • The thermostat can be mounted in both surface and sunken boxes. When mounting into a metal clad pattress or sunken box the upper and lower box lugs must be removed.
    • Ensure the thermostat is not mounted within 1m of forced heating or ventilation systems.
    • Ensure the thermostat is not in a position to be covered or isolated from the room environment. Do not mount directly next to a window.
    • Ensure the thermostat is easily accessible and does not put occupants or service engineers at risk of injury.

     

    To control a wet system a PRE9500 will need to be fitted to the radiator. This is a simple and quick process.

      Electric Panel Heaters

      Installation of panel heaters

      The positioning, in the room, of heaters and control units is critical in making sure the energy saving benefit of our products is maximised.

      Heaters should be positioned as far from the thermostat or control unit as is practically possible.

      Heaters should only be connected by an authorised person, according to valid regulations and rules.

      The heater must be installed in accordance with professional standards, and comply with the regulations in force in the country of installation.

      The appliances are class II, and protected from water splashes, to IP 24. They may therefore be installed in volume 2 of shower rooms (see Fig 1). It must be impossible for anyone using the shower or bath to reach the appliance’s controls.

      See Fig 2 for minimum distances to obstacles when positioning the heater.

      Do not use the appliance if the power cable is damaged.

      Do not install the appliance:

      • Underneath a fixed mains socket.
      • In volume 1 of  bathrooms.
      • Near curtains or any flammable materials.
      • The air outlet must be visible at the top of the appliance.
      • Below or within an absolute minimum of 300mm of a thermostat.

       

       

       

       

      FIXING

      Releasing the Heaters bracket latching bar:

      • Place the heater flat on level ground facing down, take care not to
        damage the heater.
      • Use a flat blade screwdriver to raise the tongue at the top of the bracket. Take care not to raise the tongue to far, as this will result in damage to the bracket. While holding the tongue raised in the up position, slide the bracket downwards towards the base of the heater to release the top latches.
      • Pivot the bracket up and remove from the heater.

      Fixing the heater bracket:

      • Place the latching bar on the floor upright against the wall, locate drilling holes A (see Fig 4), These show where the lower fastenings need to be located for the correct heater height.
      • Lift the bracket aligning it with drilling point A to locate the B
        drilling points.
      • Drill the A and B drill holes and insert suitable plugs if required.
      • Locate the bracket and fix in place with suitable fixings.

      Locating the Heater onto the bracket:

      • Locate the heater onto the lower latches of the bracket, the heater must be located at a 30° angle to locate into the lower latch, once the lower latches are located pivot the heater parallel to the fixing surface and locate the top latches, once the top latches are located slide the heater downwards until a click is heard indicating the heater is properly latched into place.

      Releasing the heater from the fixed position:

      • To release the heater from the bracket, use a flat bladed screwdriver to lift the latch tongue (see fig 5) away from the heater towards the fixing surface. Take care not to bend the tongue too far. With the tongue in the lifted position, lift the heater upwards, then pivot away from the fixing surface by 30°, finally, lift the heater away from the bracket.

        ELECTRICAL CONNECTION

        The power supply to the appliance is 220/230V, 50Hz/60Hz.

        • The panel heater must be connected to the mains by a 2-wire cable (Brown= Live, Blue = Neutral) by means of a suitably rated double pole isolator and a LOT 20 compliant Prefect control.
        • In humid areas such as bathrooms and kitchens the power socket must be installed at least 25 cm above the floor. The installation should be fitted with a double pole break device with a break of at least 3 mm.
        • The Heater must not be connected to the earth.
        • The appliance must be installed by a professional (a qualified electrician) in accordance with the regulations in force in United Kingdom.
        • The “no control appliance” Must be installed with a suitable thermostat for example the PRE2000 or ecostat2.
        • When fitted in conjunction with an external thermostat as suggested above the thermostat should be mounted at least 300mm away from the heater, and protected from artificial heat sources for example: Desktop computers, TV’s, Desk lamps etc. The Thermostat should be mounted between 1200mm & 1400mm. Mount in a 25mm or greater back box.
        • Once the heater has been fitted connected and tested, the heater must be run for 5 minutes to prove the unit and complete the element burn off. Oil is present on the element from manufacture, when the heater is first powered the oil will burn off and produce an amount of smoke in the process, this is normal. Ensure the area is unoccupied and that any fire detection systems are temporarily disabled then re-enabled immediately after the burn off.

        ENERGY LOCK INSTALLATION

        The heater will not function until the energy lock key (see Fig 6) has been installed into the heater. The energy lock key is supplied with the control thermostat.

        • Holding the key with the tooth at the top, note the T shape of the tooth. On the top right hand side of the heater is a plastic cover, on this cover you will see a corresponding T slot. Locate the key into the T slot on the heater (see fig 7).
        • Once the key is located into the T slot, push the key home until it is flush (see fig 8). Once the key is fitted the heater will be able to operate when the thermostat is calling for heat.
