T8A7 : No Cooling Red Chiller
To avoid serious injury follow all warnings and instructions in the manual. Wear appropriate personal protective equipment.
Visually check circuit breaker for a tripped condition.
Disconnect the valve and measure the voltage across the wires when the chiller is running, to ensure 24V is being delivered to the valve. If so, the cooling valve will likely need replacing.
Turn on chilled water supply.
Check RTD wiring.
