5.4.1.

Monitoring dew point via relative humidity 
sensor of room thermostat

Every DRT-200 room thermostat has a built in relative humidity

sensor. Take care removing the white-yellow part on the 

thermostat to make it works. 

The WTC-3 base unit continuously receives the actual relative

humidity and room temperature data from every room thermostat.

The built in program can calculate the actual dew point tempera-

ture from these data in every room. When the dew point reaches

a predefined level, the base unit will adjust the room thermostat

to a higher temperature to prevent the 

condensation. This gives the highest level of comfort and the

optimum cooling capacity.  

5.4.2.

Connect dew point sensor to DRT-200 
room thermostat

An override dew point sensor should be connected directly to the

DRT-200 room thermostat. 

Two (2) types of dew point sensor can be connected : 

Dew point sensor for dry system

Dew point sensor for wet system

This sensor must be placed in the ceiling next to the inlet pipe.

The sensor has 10m of wire that can be connected directly to the

first and second input of DRT-200. The dew point sensor also

monitors condensation in addition to the built in relative humidity

sensor.
