3.0 Installation instructions  
4.0 Operating instructions  
4.1 Thermal actuator installation  
The system should be installed by a competent person in the following  
sequence.  
1.  
2.  
3.  
4.  
Ensure that the power supply to the base unit is disconnected.  
Lift base unit cover after loosening front screws.  
Remove internal aerial.  
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.  
Remove blue thermal actuator terminals from printed circuit  
board.  
5.  
6.  
Connect thermal actuator cables.  
Reattach thermal actuator terminals in assigned order to printed circuit  
board.  
7.  
8.  
9.  
Position cables in strain-relief cable glands (see Fig 3).  
Replace internal aerial.  
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.  
Close base unit and tighten front screws  
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 humid 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. 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 made, the thermostats can be registered. First, power up the  
base unit. The green ‘PowerLED lights up.
