The Freeze Sentinel is enabled by a dip switch
and is dependant on the Room Air Sensor (kit). If
the Room Air Sensor (kit) is not installed, the
Freeze Sentinel will not operate. The FREEZE S
dip switch must be down for Freeze Sentinel
operation.
FREEZE S SWITCH DOWN = ON
FREEZE S SWITCH UP = OFF
The Freeze Sentinel turns on the resistance
heater(s) and indoor fan when the Room Air
Sensor (kit) sees 41 °F. When the temperature of
the room has risen to 46 °F, the unit will turn off.
The Freeze Sentinel will remain enabled when the
unit has been turned off by the remote Central
Desk Control.
Fan Speed (Indoor Fan)
The Indoor fan operates at one speed during unit
operation. The duct dip switch, in conjunction with
the thermostat connection, controls at what speed
the indoor fan operates.
When the green thermostat wire is connected to
the high speed fan
(GH) terminal:
DUCT SWITCH UP = HIGH FAN SPEED
DUCT SWITCH DOWN = MEDIUM FAN SPEED
When the green thermostat wire is connected to
the low speed fan
(GL) terminal:
