9.0 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.  So 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:

 Airflow figures are based on a total static pressure of 125Pa for the 26 kW model, and 50Pa for 

the 15kW and 20kW models.

 

Note:

 The maximum and minimum number of outlets detailed in Table 5 are as per AGA specification.

 

Note:

 Do not install the control wiring with the power turned on, as the fuse may blow, which would not 

be covered under warranty.

 

A.

  The  maximum  number  of  outlets 

that  should  remain  fully  open  for  a 
ceiling outlet system. 
 

B.

  The  minimum  number  of  outlets 

that  should  remain  fully  open  for 
floor/ceiling systems.
