• DM calculated on BT25.
• Additional heat signal is given when GM ≤ starts
additional heat.
• The shunt valve controls to maintain calculated
temp on BT25.
• The shunt valve controls the number of whole
seconds as the difference (calculated supply
temperature BT25 supply temperature sensor) *
shunt valve amplification. The shunt valve opens
for even numbers and closes for odd numbers.
• The mixing valve is stationary during the waiting
period.
• The mixing valve closes if DM > start compressor.
• At start up the shunt valve closes for 120 secs.
