ETTING
Temperature (summer) set-point. Used for setting the cooling set-point.
r1
Cooling differential.
r2
r3
Heating differential.
r4
Temperature neutral zone.
When the temperature measured by sensor B1 is within the neutral
temperature zone, all actuators are OFF, except in the following cases:
• Minimum ON time or the switch-off delay between the two compressors has
not elapsed yet;
• the compressors (or the valve) are operating following a dehumidification
request.
Delivery temperature lower limit.
rn
When the temperature read by delivery sensor B4 drops by 3°C below the set
limit (default = 15°C), the cold actuators (compressors or refrigerated water
valve) are switched off. The actuators are automatically restored when
temperature rises back to rn value.

Dehumidification differential.
r8
Humidity neutral zone. When the temperature measured by sensor B3 is
within the neutral temperature zone, the 0-10V output, which activates the
humidifier, equals 0 and dehumidification is not active.
By using parameters
between the value measured by the sensor and the effective value measured by a precision instrument.
