Installation recommendations
1. For the controller to count heat output, install additional CT6 sensor and connect to T4 input.
2. Connect the H pump to the H output via the relay. It is necessary to use a relay type 6VDC RM85-
2021-35-1006.
Setting recommendations
1. During anti-freeze function, the P2 exchanger pump will work longer than the P1 collector pump by
double tDLY time. So select this parameter value that after P2 is stopped, the temperature of glycol
in exchanger is not lower than 0°C, as it may damage the exchanger. If there is a risk that such
situation may happen, switch off antifreeze function for the pool system.
Antifreeze function in pool circuit (with priority) may be used only at high awareness. Wrong
settings or unfavorable conditions may damage the exchanger. Always consider all factors like,
e.g., solar work fluid with below-zero temperature in the exchanger.
