user expertise.
It is important that all information in this chapter is read sequentially by the installer and that the system is configured as
applicable.
10.1 DIP switch settings overview
10.1.1 Function setting
DIP switch S1,S2 and S4 are located on the main control hydraulic module board (see "9.3.1 main control board of hydraulic
module").
Switch off the power supply before making any changes to the DIP switch settings.
10.2 Initial start-up at low outdoor ambient temperature
During initial start-up and when water temperature is low, it is important that the water is heated gradually. Failure to do so may
result in concrete floors cracking due to rapid temperature change. Please contact the responsible cast concrete building
contractor for further details.
To do so, the lowest water flow set temperature can be decreased to a value between 25°C and 35°C by adjusting the FOR
SERVICEMAN. Refer to 10.5.12 "SPECIAL FUNCTION" .
