9. d or damp e g bathrooms thermostats must be placed as far from moisture sources as possible 3 3 Pre installation Thermostats must be registered in the base unit before being placed in individual rooms When registering thermostats it is important that the room in which they are to be placed is written or marked on the rear of the thermostat Thermostats can then be registered in turn The channels to be used for individual rooms must therefore be decided in advance Note refer to section 4 3 for registration instructions Fig 2a Thermostat location Fig 2b Thermostat installation 4 0 Operating instructions 4 1 Thermal actuator installation 1 Ensure that the power supply to the base unit is disconnected 2 Lift base unit cover after loosening front screws 3 Remove internal aerial 4 Remove blue thermal actuator terminals from printed circuit board 5 Connect thermal actuator cables 6 Reattach thermal actuator terminals in assigned order to printed circuit board ve Position cables in strain relief cable glands see Fig 3 8 Replace internal aerial 9 Close base unit and tighten front screws Fig 3 Push cable through cable gland 4 2 Base unit installation Once the base unit has been mounted on the wall all thermal actuators have been connected and any connections for pump and boiler control have been mad

13. strated above in Fig 1 2 3 Aerial Normally the base unit uses a built in aerial The location of the base unit is therefore important for the range which can be increased by equipping the base unit with an external aerial An external aerial must be used if the base unit is located in a metal cabinet 3 0 Installation instructions The system should be installed by a competent person in the following sequence 3 1 Base unit Install the base unit first Mount the base unit above the distribution manifold either direct on the wall or inside a wooden or metal distribution cabinet Ensure that the base unit is mounted horizontally that there is easy access to the control panel and thermal actuator connections and that the base unit cover can be easily removed Fix the base unit to the wall using two screws The base unit must be connected to a 230 volt supply via a double pole switch socket outlet If it is installed in a metal distribution cabinet an aerial should be installed outside the cabinet in order to improve radio communication 3 2 Thermostat installation Thermostats should be mounted on an internal wall at a height of 1 2 1 5 metres above the floor using screws and fixings Thermostats must not be placed on an external wall or near heat sources such as television and stereo sets ovens or similar Thermostats should not normally be placed where they can be affected by direct sunshine In rooms that are very humi
14. tration thermostats transfer their ID numbers to the base unit The use of ID numbers also prevents the base unit from reacting to signals received from neighbouring systems or other systems based on radio technology Thermostats are battery powered and thus fully mobile making it easy to re configure the system if required The system is CE marked and approved for use in all EU and former EFTA countries The actual temperature is measured by the thermostat When the actual temperature is lower than the set temperature a command for heat is sent to the base unit Temperature can be set between 6 C and 30 C A function switch on the thermostat allows day timer control or night to be selected The day setting allows normal operation the timer setting allows time controlled night set back to be used and the night setting permanently lowers the temperature setting by 4 C Thermostats are supplied with pre installed batteries Before being taken into use thermostats are dormant and only begin measuring temperature and transmitting data on being registered in the base unit for the first time The purpose of this dormant state is to minimise energy use during storage and to avoid unnecessary radio transmission On being installed for the first time thermostats automatically enter test mode so that transmission can be tested immediately Battery life is guaranteed by the manufacturer to be at least 5 years A complete system is illu
