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.
0.1 20.0 °C 0.2
rn
Delivery temperature lower limit.
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

value.
