Thermostat RT 115
RT 115 Thermostat
017R9322
Application
The thermostat type RT 115 is designed for control of forced ventilation
in livestock buildings and hencoops.
The thermostat has the effect of constant ventilation as long as the room
temperature exceeds the temperature setting.
If the room temperature is lower than the temperature setting, there wil only
be intermittent ventilation. The cut-out period is extended when the room
temperature falls, and if the temperature falls, and if the room temperature
is 2 °C lower than the temperature setting, the thermostat cannot start the
fan.
The special kind of control offered by RT 115 is due to the extra sensor
(B) inside the thermostat housing. Alongside the sensor there is an electric
heater (C) which is cut in when the fan is cut out and vice versa.
Installation
A set of Pg13.5 cable gland is attached to the RT in a separate bag. To ensure IP66 (units with automatic reset) or IP54 (units with external reset) grade of RT enclosure it is necessary to assemble this gland as shown in the fig. 3. If this gland is not used with a cable, a metal blinding should be also assembled.
Fitting
The thermostate should be fitted in the centre of the building, but in such a position that the body heat from the larger animals cannot directly influence the thermostat.
Setting
Set the thermostat by rotating the knob (5) for a temperature which is approx. 1 °C higher than actually desired in the building.
- If the fan then runs continuously, the capacity of the fan is to low of the outdoor temperature is too high
- If the fan runs intermittently, the plant operation should not be interfered with until a stable room temperature is reached. If the room temperature is then too high or too low, resetting is done
- If the fan does not start, the room temperature is too low to permit ventilation.
