Charge pump
The charge pump (not included in the product) is
powered and controlled from the indoor module/control
module. It has a built-in frost protection function and,
for this reason, must not be switched off when there is
a risk of freezing.
At temperatures below +2 °C the charge pump runs
periodically, to prevent the water from freezing in the
charge circuit. The function also protects against excess
temperatures in the charge circuit.
