8. THERMOSTAT INSTALLATION
All Brivis heating systems can be controlled by various Brivis Thermostats, each explained in detail below. A
Thermostat inside the house is wired to the control module in the heater. The Thermostat monitors the temperature
in the house and switches the system ON and OFF in order to maintain a set temperature. Therefore, it must be
positioned correctly.
•
Install in the living area:
It is important that the Thermostat is placed in a position that will provide the most
accurate reading of the temperature, i.e. in the area most often used for family living.
•
Attach on an internal wall:
The temperature difference on an external wall can also affect it, so always mount
it on an internal wall. Keep hole in the wall for the wiring as small as possible to prevent draught from within the
wall cavity affecting the temperature setting.
•
Get the height right:
The Thermostat should be approximately 1500mm above the floor level.
•
Avoid hot spots:
Keep it as far away as possible from warm air outlets, radiation from the sun, fireplaces,
radio and television sets, or warm pipes and duct running in the wall behind it.
•
Avoid cold spots:
Keep it as far away as possible from draughts caused by doorways, stairwells, windows or
return air inlets.
•
Avoid dead spots:
Keep it away from areas of less than normal air circulation, e.g. behind doors, in alcoves or
corners.
•
Interference from other electrical connections:
Ensure the Thermostat and wiring is kept away from other
electrical, data and antenna cables. This includes keeping the Thermostat’s wiring away from the spark igniter
loom within the heater’s cabinet.
•
Use the right cables:
Ensure the cable is 0.75mm² in cross section and less than 100m in length.
NOTE
DO NOT
install the control wiring with the power turned on, as the fuse may blow, which would
not be covered under warranty.
8.1 WIRING THE MANUAL OR PROGRAMMABLE THERMOSTAT (HEATING ONLY)
Brivis Manual and Brivis Programmable Thermostats can be wired directly to a Classic heater for heating only
applications.
NOTE
Only use Brivis Thermostats, as any failure relating to a non-Brivis Thermostat will not be covered
under warranty.
To connect the Thermostat to the unit:
• Run twin core cable no less than 0.75mm² in cross section from the heater
“W & R Terminal Block”
to the
thermostat location.
• Remove thermostat backing plate from the front cover and mount on the wall.
• Draw wires from the wall cavity, connect W & R terminals on the heater
“W & R Terminal Block”
to the W & R
terminals on the thermostat, refer to Diagram 8 and Diagram 9.
• Insert batteries and mount thermostat front cover onto the backing plate.
• For more information refer to the Installation Guide and Operating Manual supplied with the Brivis Manual or
Programmable Thermostats.
