Installation recommendations
1. For the controller to count heat output, install additional CT6 sensor outside circuits of three-way
valve
H and connect it to T4 input. The sensor should be installed possibly close to the H outlet.
2. The valve should be connected so that the controlled relay connected to output H (H=ON) set will
set the valve in pool loading position. Reverted connection will damage the system.
Setting recommendations
1. If the used three-way valve has switching time longer than 120sec, set maximal value for tVALVE .
2. If the used three-way valve has near zero switching time, set minimal value for tVALVE
3. When the circuits are being switched ( tVALVE time) the collector pump is not working and the
circuit receives no heat. Pay attention to collector heat up time and if required set shorter tVALVE
time.
4. During anti-freeze function, the exchanger pump will work longer than the 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.
