Installing a Call Flex Kit

Time Clock Management - Heaters Equipped With HP7 Microprocessor
The CALL-FLEX is installed to manage the time clock to the desired heating style of the pool heat
pump owner. With CALL-FLEX, owners select one of three heat modes:
The heater "overrides" the filter pump timer when the pool water drops below the
temperature set point. Two hours after the initial thermostat "call" for heat, the
heater starts. This delay prevents nuisance pool pump cycling.
In CALL MODE, the heater will operate mostly at night when the greatest heat loss
occurs and the heater is least effective. If the owner prefers daytime operation,
the FLEX MODE may be more productive.
The heater "extends" the heating hours beyond the timer settings. If the heater is
not running when the time clock expires, the pool pump will remain off until the
next timed cycle. If running, it continues the pool and heater operation until the
set point is attained, then stays off until the next timed cycle.
The FLEX MODE is very convenient after cold snaps, if the blanket was left off the
pool, or at initial start-up when the heater must run beyond standard filtering hours to
elevate the pool temperature.
Operation is controlled by the time clock.
