* The controller controls the H* and H pumps in parallel through a common relay.
Installation recommendations
1. For the controller to count heat output, install additional CT6 sensor and connect to T4 input.
2. The H* and H pumps must be connected to the H output by a common relay to ensure their
parallel operation. It is necessary to use a relay type 6VDC RM85-2021-35-1006 .
Setting recommendations
1. During anti-freeze function, the H* exchanger pump and parallel H pump will work longer than the
P1 collector pump by double tDLY time. So select this parameter value that after H* and H pump
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.
