- The Call-Flex option is installed to automatically adjust the run time of the water circulator pump, and heater, based upon changing weather conditions. Without Call-Flex, as weather conditions grow progressively cooler during winter months, or when unusually cold weather occurs, the run duration of the circulator pump may require manual adjustments to permit the heater to maintain or reattain desired water temperature (the water pump must be running in order for the heater to operate). Likewise, without Call-Flex, one must remember to reset the pump run controls following the cold weather event. The Call-Flex option greatly reduces the need for seasonal, manually-made, pump run time adjustments.
- The 0030-
LEDSkit is compatible with digital versions of AquaCal heat pump controllers. It is not compatible with analog heat pump controllers.
