5.4 Time delay of compressor
The heat pump is equipped with a 3 minute built-in solid state restart delay once the compressor is
turned off and a 1 minute buit-in solid state compressor running time. Both to protect control circuit
components, to eliminate restart cycling and contactor chatter. This time delay will automatically
restart the unit approximately 3 minutes after each control circuit interruption or after a compressor
running period of 1 minute. Even a brief power interruption will activate the solid state 3 minute
restart delay and prevent the unit from starting until the 3 minute countdown is completed. Alarms
or errors during time delay have no influence. Power interruptions during the delay period will cause
a restart of time delay.
6. Operation and Use
6.1 Before operation
The desired temperature can directly be set with the arrow keys. The setting will automatically be
stored in memory. A choice can be made between °C and °F as follows:
1. Enter the parameter menu by pushing the up and down button simultaneously.
2. Go to the fahrenheit parameter (P02) by pressing up/down buttons.
3. Press the on/off button to enter the parameter set mode.
4. Adjust the parameter to the desired value. When the parameter is set to 1, all temperatures
should be in °F instead off °C.
5. Press the on/off button to leave the parameter set mode.
6. Exit the parameter menu by pushing the up and down button simultaneously.
6.2 Initial startup
The following steps need to be taken at startup (after verification that all the connectionsare made
to the according specifications:
1. Turn on the filter pump. Check for possible water leakage and water flow to and from the
swimming pool.
2. Put the power plug into the outlet and switch the heat pump ON. The unit will start after the time
delay (see 5.4).
3. Verify after a few minutes that the air exhausted by the heat pump is becoming cooler.
4. Allow the unit and pool pump to run 24 hours per day until desired pool water tempe0,5°C
is reached. When the set temperature is reached, the unit shuts off. The unit will automatically
restart when the pool temperature drops 0,5°C below set temperature.
