Add the Intermatic Freeze Sensor (178PA28A) to the Intermatic P1353ME
Mechanism installations where below-freezing outdoor temperatures are a
concern. The sensor is designed to protect the pool and spa equipment
and plumbing against freeze damage. The sensor plugs into the circuit
board on the back of the Intermatic control mechanism (P1353ME) and
turns ON the filter pump when air temperature drops below the programmed
temperature. The freeze programming mode will not appear unless the
sensor is plugged into the clock.
