Minimum voltage of the fan output:
Display shows
“min vdc analog output fan”
and the value of the
minimum voltage of the fan ramp.
Please select the desired value of the minimum voltage of the fan ramp.
(This is the “zero” value)
The minimum value is restricted by the maximum value. (step #35)
Range: 0.0 to 10.0 Volt
Increment: 0.1 Volt
Default value: 0.0 Volt
35
Maximum voltage of the fan output:
Display shows
“max vdc analog output fan”
and the value of the
minimum voltage of the fan ramp.
Please select the desired value of the maximum voltage of the fan ramp.
(This is the “span” value)
The maximum value is restricted by the minimum value. (step #34)
Range: 0.0 to 10.0 Volt
Increment: 0.1 Volt
Default value: 10.0 Volt
36
Set fan speed automatic mode enable or disable:
Display shows
“enable fan auto mode”

Display shows
“fan auto timeout minutes”
and the automatic shutoff delay
value (in minutes) when there is no demand.
Please select the desired value of the automatic shutoff delay.
Range: 0 to 15 min.
Increment: 1 min.
Default value: 2 min.
38
External sensor selection:
Display shows
“extern sensor temper”
.
Please select which sensor is rewired to the analog input: OFF (input
none rewired), t10.0 (external temperature sensor 10.0
K
Ω
)
When nothing “
OFF
” is selected, the thermostat is controlled by is
internal temperature sensor.
When external sensor “
t10.0
” is selected, the thermostat is controlled by
an external temperature sensor.
If you have selected OFF, go directly to step #40.
Default value: Off
39
C
External temperature sensor calibration:
Display shows
“extern temper sensor offset”
and temperature read by
external temperature sensor.
If the sensor is not connected or short circuited, the display shows
“
Eror
”
.
You can adjust the calibration of the external sensor by comparison with a
known thermometer.
Range: 0.0 to 50.0ºC [41.0 to 122.0ºF]
(max. offset ± 5 ºC)
Increment: 0.1ºC [0.2ºF]
40

Display shows
“Select occ contact”
. Moon symbol is also displayed.
You can choose NO (normally open) or NC (normally close) contact.
Default value:
Normally open (NO)
41
No occupancy derogation time :
Display shows
“no occ delay overide minutes”
and the derogation time in
minute. NSB symbol is also displayed.
Please select the desired derogation time.
