Product details
Product details:
The device software has an independent control of one or two heating zones programmed on a weekly basis apart of operating parameters for each zone. The device has a sensor calibration and hysteresis adjustment option.
System control based on readings of the heated space temperature, air and ground temperature.
The device has a digital display for easy operating parameters setup and the current temperature reading from the sensor. The controller software allows you to set a single parameter called “trigger point” at the specified temperature range setting after selecting a level of the upper and lower temperatures.
The TVR 295 controller is equipped with a single-channel contactor and can directly attach circuits whose power output does not exceed 3500 W or indirectly by an additional voltage contactor.
The controller can be used to protect:
- roofs
- gutters
- downpipes
- drainage channels
- stairs
- sidewalks
- driveways and loading ramps
- wherever air temperature reading is enough to monitor the de-icing system
The controller operates with two types of sensors:
- CZP 200 - air sensor in the hermetic cover on the wall
- CZN 200 - cable sensor
The TVR 295 controller complies the European standard IEC 60800 1998
