10 - “SUMMER / WINTER” MODE SWITCHING LOGIC
10.1 - COOLING / HEATING SWITCHING
• Four logics are present to select the thermostat operating modes, Rhich are defined Rhen parameter “
P00
” is configured:
- Local manual : user choice made through the Cey .
- Remote manual : depending on the Digital Input 1 status (contact logic: see configuration parameters of board).
- Automatic depending on water temperature (2-pipe).
Note: in case of Rater sensor alarm, the controller returns to
the Local mode temporarily (manual).
- Automatic depending on air temperature (4-pipe):
Where
- Set is the set point programmed for the climate,
- ZN is the neutral zone (parameter
P03
).
Note : the value displayed for parameter
P03
is to be
divided by 10.
• The thermostat operating mode is indicated on the display by
the symbols (Cooling) and (Heating).

11.1 - OPERATING SPEED SELECTION
• Using Cey it is possible to select the folloRing speeds:
- AUTO Automatic fan speed : depending on the set temperature and the room air temperature.
- 1 = loR speed.
- 2 = medium speed.
- 3 = maximum speed.
• Note:
In the case of fixed speed, the fan on/off logic Rill be equivalent to the automatic logic.
11.2 - ACTIVATION ACCORDING TO THE WATER TEMPERATURE (if sensor connected)
• Fan operation may be connected to the installationgs Rater temperature control. Based on the operation mode, different
heating or cooling thresholds Rill be enabled.
• The absence of this condition Rhen queried by the thermostat Rill cause the symbol of the mode currently active ( or
) to flash.
The enabling signal is ignored:
- Water sensor not provided (
P04
= 0) or in alarm status.
- In the cooling mode Rith 4-pipe configurations.
