Section 4. OPERATION – Automatic Ventilation
Room Control type: TB/TS/K-BIDDLE for manual Temperature & Automatic
Ventilation.
Also incorporates a room temperature sensor
DO NOT SWITCH UNIT OFF AT THE MAINS except in times of emergency
Unit Functionality:
In this format of operation the unit is effectively switched ON or OFF by the use
of an external timer, PIR sensor or BMS. See individual connection information.
All ventilation rates are controlled automatically and there is no manual
control. A CO2 sensor is required in the unit with this form of control. This limits
the quantity of fresh air to just that required for the occupancy of the room for
increased energy efficiency. The Sensor is supplied built into the units and
should be removed and mounted remotely on chassis units.
See section headed ‘Connection to CO
2
Sensor’ for more information.
Manual adjustment of Room temperature is controlled by the set-point
adjuster, which can be rotated between the 18°C and the 24°C settings.
BMS control can also be used to remotely re-scale the minimum and
maximum set point positions (e.g. 19°C min / 23°C max) for increased energy
efficiency.
The unit will operate in either Normal ‘occupied’ operating mode or
‘Unoccupied’ set-back mode, exactly as the Manual / Stand Alone unit
does. In Unoccupied set-back mode the unit operates to satisfy the set
back temperature or ‘night time cooling requirement only.
