Return Pump Timer Controls to Normal Settings

3.Select POOL or SPA & HEAT or COOL, Raise or Lower Associated Thermostat:

♦Position the POOL/OFF/SPA toggle towards the POOL or SPA thermostat knob (depending on which body of water you are preparing to heat or cool).

♦For Heating, move HEAT/COOL toggle to HEAT, then turn the selected pool or spa thermostat dial clockwise to its highest setting. As soon as the thermostat setting is above the temperature of the water, the heat pump will begin to operate. See note below if heater does not start

immediately.

♦For Cooling, move HEAT/COOL toggle to COOL, then turn the selected pool or spa thermostat dial counterclockwise to its lowest setting. As soon as the thermostat setting is below the tempera- ture of the water, the heat pump will begin to operate. See note below if heater does not start immediately.

Note- Heater Controls Contain a Solid-State Time Delay Module

This time delay feature prevents damage to the compressor should electrical power be re- peatedly interrupted, or if the heat pump were to come under any other circumstances leading to an on-off-on-off cycling condition. If the heater has water flow and electrical power sup- plied, but the heater does not immediately start upon turning the thermostat to its highest (or for cooling, lowest) setting, wait five (5) minutes; the time delay module may be preventing the heater from operating. Likewise, once the heater is operating, if the thermostat is turned past the present water temperature, the heat pump will shut off. Subsequently, the heater cannot restart for approximately five (5) minutes– no matter how far the thermostat is rotated.

4.Ensure Uninterrupted Pump Operation During Initial Warm-Up or Cool-Down Period:

♦Permit pool or spa circulator pump to run continuously until the desired water temperature is reached (with a pool, this may take several days).

♦Continuous pump operation will likely require temporarily resetting (or removing completely) the trippers on the time clock, thus allowing nonstop operation. When an external electronic controller operates pumps and valves, follow the controller manufacturer's instructions to ensure temporary, uninterrupted pump operation.

♦Throughout the warm-up or cool-down period, keep the selected pool or spa thermostat dial set to its maximum heating or cooling position.

5.Desired Water Temperature Reached– Set Thermostat to Maintain:

♦If Heating, once the desired water temperature has been achieved, rotate the thermostat knob very slowly counterclockwise until the unit (just) shuts off.

♦If Cooling, once the desired water temperature has been achieved, rotate the thermostat knob very slowly clockwise until the unit (just) shuts off.

♦The heater will automatically maintain the pool or spa at the selected temperature.

6.Return Pump Timer Controls to Normal Settings:

♦Reset pump timer controls for normal daily hours of operation.

♦During cooler or cold weather conditions, it may become necessary to extend the daily hours of pump operation; doing so will help the heater to keep up with increased heat losses. Extending pump operation hours for cooling is not generally required.
