5.7 Heater Thermistor Installation
•
For Brivis StarPro Heating only applications the heater
thermistor must be installed in accordance with the
instructions for the heater
•
For Dual Comfort systems (Brivis StarPro Heating and
Brivis ICE Add-On applications), the heater thermistor must
be installed in the
discharge pop (outlet) of the cooling
coil . Refer to the associated Brivis ICE Installer Manual for
details
•
Amongst other primary functions, this thermistor also
provides Low Temperature Limit protection. If the cooling
coil temperature remains at or below 7
o
C for 3 minutes, the
compressor will cycle off for a minimum of 5 minutes, and
until the cooling coil temperature reaches 10
o
C
•
During this off cycle time the indoor fan will continue to run
•
If this condition persists, confirm the system design and/or
operation is able to maintain the minimum recommended
cooling airflow requirements
5.8 Brivis Evaporative Cooling
Operating a Brivis evaporative cooler and a Brivis heater
requires the two left terminals (TW1 & TW2) connected to the
heater and the two right terminals connected to the cooler.
•
Zoning is not available during Evaporative Cooling mode
•
The Master Controller, or any other ZonePlus NC-6, where
fitted, will operate a Brivis Evaporative cooler with all normal
features and functionality
5.9 Zone Dampers
24 Volt Drive Open / Drive Closed zone dampers are to be
field supplied by installer.
Note: Zone dampers must be insulated in accordance with
local codes, particularly in cooling systems to prevent
