Water Testing Pump Output
For an individual pump system only used for pool heating.
The heat pump is fitted with a smart controller output which allows water testing to occur after a set period
of time after the heat pump has reached temperature. This can be activated through the internal
settings but is not set as default.
E.G the pump runs every hour for 3 minutes to test the water temperature, if the temperature is below set
point the pump will continue to run and heat the pool, when the temperature is achieved the heat
pump and pump will switch off and testing time will begin again.
For further information please contact your sales representative.
External input
Some units come with a built-in external input labelled 5 and 6. This comes standard as a looped
connection and is used for an external signal.
This is a volt free contact and with continuity through connections 5 and 6 it will signal the unit to operate.
Note. It will only activate if the timers are activated in parallel with the input.
This external input allows the system to run with most automation systems or in combination with solar
systems where there is a priority heat source.
For more information please contact your local sales representative or contact technical sales
Note: The installer should connect 1 parallel with 2 (as above picture). To start the water pump, condition
1 or 2 is connected. To stop the water pump, both 1 and 2 should be disconnected.
