System Set Up
[Floor dry up function]
The Floor dry up function automatically changes the target hot
water temperature in stages to gradually dry concrete when this
particular type of underfloor heating system is installed.
Upon completion of the operation the system stops all the op-
erations except the Freeze stat. operation.
For Floor dry up function, the target flow temp. of Zone1 is the
same as that of Zone2.
Disconnect wiring to external inputs of room thermostat, demand control, and outdoor thermostat, or the target flow temperature
may not be maintained.
