The H5TC Controller is designed to switch a 240Vac pump and control a heater via a relay contact rated to 1A @ 24Vac. This unit is designed to be connected to a Chlorinator output via a secondary power lead (2 Pin Black Cable). When the chlorinator pump output is turned on, the H5TC switches on the pump and the heater is turned on. This is dependent on the heating times and temperature limits as set on the H5TC.
When the chlorinator turns off, the H5TC continues to operate to meet its own heating times & temperature limits. If the temperature limit is reached or if outside of heating times, the heater is switched off. A heater cool-down (if required) continues to operate the pump for an adjustable period and if the chlorinator is not currently active, the unit will stop the pump and start an adjustable sample wait period.
