Setting the UFH circulating pump speed
Setting the speed of the UFH circulating pump is essential in ensuring the capacity of the Heat Pump
is not effected. The required pump speed will differ from install to install and careful setup is needed.
The pump control mode ‘Constant Speed’ is recommended and its best practise to start the pump on
it’s lowest speed and increase as necessary.
1. Set the pump control mode (A), using the operation button (B).
2. The speed setting is indicated by the LED (C).
3. Check the Delta T across the Heat Pump is 5 (CH-flow - CH-return = 5).
