Hysteresis of the setpoint [°C]
Register 29 (BIT 0) = 0
Not cold demand
Setpoint temperature [°C]
Register 4
Bypass (cold mode)
• Register 8: Tint/Text differential for free-cooling [read/write].
− The value sent is the differential value (2.0ºC to 10.0ºC) multiplied by 10 in 16-bit binary.
Default value: 50 [5.0 ° C]. Hysteresis: 2ºC.
• Register 9: Minimum outside temperature [read/write].
− The value sent is the minimum temperature value (0ºC to 18ºC) in 16-bit binary.
Default value: 8 [8ºC]. Hysteresis: 1ºC.
It allows defi ning a minimum value of outside temperature from which the bypass drive does not occur, avoiding situa-
tions of thermal discomfort inside.
• Register 10: Fan speed [read/write].
− The value sent is the speed value (10% to 99%) in 16-bit binary.
Default value: 50 [50%]. [Register 11 ≤ Register 10 ≤ Register 12].
• Register 11: Minimum fan speed [read/write].
− The value sent is the minimum speed value (10% to 99%) in 16-bit binary.
Default value: 10 [10%]. [Register 11 ≤ Register 10 ≤ Register 12].
• Register 12: Maximum fan speed [read/write].
− The value sent is the maximum speed value (10% to 99%) in 16-bit binary.
Default value: 99 [99%]. [Register 11 ≤ Register 10 ≤ Register 12].
