Temperature Indicator/Controller (Thermostat)
Combines a precise temperature control and easy programmability with a convenient LED temperature
readout that indicates system liquid temperature (2_F Differential). To adjust thermostat, see next section.
1. CONTROL POWER SWITCH/LIGHT
A simple ON/OFF push--button that switches power to the 24 volt control circuit. When the switch is
pressed, the white light on the push--button illuminates to indicate that Chiller Control Power is present.
Light is no longer illuminated when button is returned to ”OFF”position.
2. COOLING LIGHT
A green light that illuminates to indicate that the refrigeration system is operating. This light may cycle on
and off in response to the thermostat or in response to HOT GAS BYPASS if the unit is equipped with the
hot--gas bypass option.
3. SAFETY LIGHT
A red light that illuminates to indicate that a problem is present with the chiller. The safety light will illumi-
nate under the following conditions:
A. High Refrigerant Pressure
B. Low Refrigerant Pressure
C. Low Reservoir Level (Alarm also sounds)
D. Low Evaporator Temperature
It is important to note that each of these conditions will shut down the ”CH”unit. For additional protection to
your equipment, some models are equipped with a LOW FLOW INTERLOCK which terminates power to
your equipment in the event that liquid flow from the ”CH”unit drops below 1.25 GPM.
