Programmable thermostat HELIOS VENTILATEURS
Electronic thermostat EST with various choices to control an auto transformer KTFL . Combines the modern computer controlled ventilation control with the energy saving robust transformer technology.
Controller function
- Temperature controlled five step fan controller via KTR.. units. Limiting of control range through setting a minimum and maximum air rate (voltage). Minimum air rate can be switched on and off.
- Ventilation shutter control (analogue 0... 10 V)
- Control of a frequency inverter (analogue 0... 10 V)
- Heating thermostat
- Temperature control (too low and too high temperature with outside air compensation)
