9.35 Internal Heater
HEATING
ON
Internal heating during standstill to prevent
condensation in the HYDROVAR
If “ON” is selected (should be the general configuration) a heating resistance
(approx. 10 watt) is switched on, when the motor is at a standstill and the supply of the
HYDROVAR is O.K.
Notice: If the HYDROVAR is cut from the supply the internal heater doesn’t work!
So if the HYDROVAR isn’t used for a longer time (e.g. winter season) it shouldn’t be
disconnected from the power-supply.
