DESCRIPTION OF THE FUNCTIONS
CONTROL FUNCTIONS:
The ventilation unit can be operated from a separate Smart control panel or a Smart cooker hood.
When the ventilation unit is controlled from the cooker hood in the Home/Away/Boost modes and cooker hood damper open time can be set to 30, 60 or 120 minutes.
The supply air temperature setpoint can be changed from the Smart control panel. The post heating can be disabled from the control panel.
SAFETY FUNCTIONS:
– Overheating protection for the post heater: Electrical heater is equipped with a automatic thermostat TZA1 and a thermostat TZ03 with manual reset (set value 60 °C).
– The fans have automatic overtemperature protective devices.
REMEDIAL MEASURES TO TAKE IF THE SAFETY EQUIPMENT TRIPS:
– If an overheating protection with manual reset trips, locate and correct the fault; then press the reset button inside the ventilation unit.
– The automatic overheating protections of the fans will reset themselves when the temperature has dropped below the setting value.
REMOTE OPERATION: Study the ventilation unit manual and the list of parameters for Modbus.
