TEMPERATURE SET-POINTS
To change set-points, you have to input the “USER” password to access the “SetP” menu in programming mode.
SEtP SETTING
Minimum Maximum Measurement
unit
Default
r1
Temperature (summer) set-point. Used for setting the cooling set-point. 0 50 °C 23
r2
Cooling differential. 0.1 11.0 °C 1.5
r3
Heating differential. 0.1 11.0 °C 1.5
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.
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 rn value.

HUMIDITY SET-POINT
SEtP SETTING
Minimum Maximum Measurement
unit
Default
r5
Humidity set-point 20 90 %R.H. 50
r6
Humidification differential. 1 20 %R.H. 5
r7
Dehumidification differential. 1 20 %R.H. 5
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.
0 20 %R.H. 10
CALIBRATION AND SETTINGS
By using parameters
6, 7, 8, 9 the measurement of the sensors can be corrected if a difference is noted
between the value measured by the sensor and the effective value measured by a precision instrument.
