9.2 Wiring the Brivis Programmable Thermostat (ADD-ON & FAN ONLY)
The Classic control board does not have provision for “
Add-On
” cooling or “
Fan Only
” operation. For “
Add-
On
” cooling or “
Fan Only
” operation the unit must be configured.
To facilitate Add-On Cooling or Fan Only operation an additional accessory,
‘ACC LOOM ADD-ON RELAY
CLASSIC’ (Brivis Part No. B063283)
must be fitted.
To configure a BX3 or 2PWN unit for “
Add-On
” cooling refer to Diagram 12.
To configure a BX3, 2PWN, UF3, or DF3 unit for “
Fan Only
” operation refer to Diagram 12 and omit the “
Y
”
connection. For more information regarding connection of the Add-On relay refer to the installation
instructions supplied with ‘ACC LOOM ADD-ON RELAY CLASSIC’ (Brivis Part No. B063283
).
