Hayward GLC-1P-A Solar Pool Heating Control
This is a combined control system and valve actuator kit designed for solar pool heating systems made by Hayward. It includes a controller that monitors temperature sensors and a 24 V actuator that drives a three-way valve to route flow when solar heat is available.
Key details:
OEM model: GLC-1P-A
Includes controller + actuator + 3-way valve and associated sensors
Designed for automatic switching between pool circulation, solar heating, or bypass depending on temperature differential
Suitable for 1½″ & 2″ ports on the included valve
Typical usage: solar pool heating installations where the control must sense collector roof temperature and pool water temperature, then open or close the valve accordingly
