3. COOLING LIVING SPACE WITH
BLOWING THE COOL OUTSIDE AIR
INTO THE LIVING SPACE
Differential thermostat controls the ventilator.
3.1 BASICS
The thermostat enables setting two parameters:
1. Regulation of minimum tem pera ture in living space 5°
to 85°C.
This temperature is defined by T2 sensor witch is generally
mounted in reference position in the room.
2. Regulation of difference of out side and inside temperature
0K to 15K.
With this regulation you define how much the value of the source
temperature (outside air) should be lower than inside temperature
that thermostat switches on the ven ti lator.
3.2 OPERATION
DTC 200/2G single differential ther mo stat measures the
temperature of outside air and inside air.
Cooling effect is provided, when cooling source temperature is
lower than the temperature of in side air. Consequently minimum
difference should be 2K.
When the temperature of outside air is below the temperature
of in side air the ventilator switches on.
The thermostat switches off the ventilator if pre-set minimum
tem pera ture is reached (adjustable from 5° to 85°C).
3.3 SENSORS INSTALLATION
Installation of outside sensor T1
Install it next to entrance of suction opening of the ventilator or
next to entrance of suction channel.
Installation of inside sensor T2
Install it on desired height, approximately on the centre in the
room space at least 0,5m from the ceiling. If not install correctly
the sensor will not detect real room temperature.

3.5 ELECTRIC CONNECTION
Before each interventions in the thermostat first
disconnect the main power!
1(1)A, 250V
Grounding wires should be connected to special terminal pins
situated on left side of terminal strips.
The thermostat is designed for fixed installation. When
performing electric installation, an element should be
inserted which enables at least 3 mm separation of
thermostat from the mains (switch or socket). Prior to each
intervention in the thermostat, first disconnect it from the
mains.
