Temperature controller

Temperature controllers regulate fans depending on the air temperature at the controller. A controller measures the ACTUAL temperature and adjusts the motor speed of one or more fans to maintain the set temperature by supplying fresh air. If the ACTUAL and SET temperature are identical, the fan(s) will continue to run at the preset minimum speed (limit) or optionally switch off.

Working principle - Controls one or more fans depending on the air temperature at the fan.
Use - If the ACTUAL temperature rises above the SET temperature, the control system switches the fan(s) up continuously. If the ACTUAL temperature reaches the SET temperature, the system switches to the set minimum speed. If the ACTUAL temp. falls 3K below the SET temp., the system switches off the fan(s) or continues to run at the preset min. speed (selectable).
Expansion - Control output 0 V (off) - 10 V (max.) for expansion by power unit in 6 A steps.
Voltage - 230 V ~ 50 Hz. CTR 6: max. load 6 A. Minimum load 0.2 A.

CTR 10: max. load 10 A. Minimum load 0.5 A.
Temperature range - setting range from +5° to +35 °C, ambient temperature max. 40 °C.
Spreading - Adjustable proportionalitätsbereich 2 K to 10 K (spread).
Special version - available with inverse function instead of Kühlen heating (with switchable output 230 V ~ 50 Hz)).
Special version - available with contact for fire alarm panel (in case of fire the system is automatically switched off).
