PREHEATING FOR FLOOR
MENU > FOR SERVICEMAN > SPECIAL FUNCTION > PREHEATING FOR FLOOR
Before floor heating, if a large amount of water remains on the floor, the floor may be
warped or even rupture during floor heating operation, in order to protect the floor,
floor drying is necessary, during which the temperature of the floor should be
increased gradually.
During first operation of the unit, air may remain in the water system which can cause
malfunctions during operation. It is necessary to run the air purge function to release
the air (make sure the air purge valve is open).
T1S sets the heat pump leaving water set temperature in preheating for floor mode.
t_FIRSTFH sets the duration of preheating for floor mode.
