Analog Inputs
The following items can be used for each input:
[Not Used]..........................Not used
[S.P Offset]......................... Room temperature set point offset – 4-20mA signal.
[F.A Offset].........................Minimum fresh air set point – 4-20mA signal.
[Weather T.] ....................... Entry for a Meteorological temperature sensor
[Weather H.].......................Entry for a Meteorological humidity sensor
[Free NTC] ......................... Free temperature probe connection
[Free Hr.]............................ Free relative humidity sensor connection
Ambient Temperature Set Point Offset – 4-20mA Signal:
The 4-20mA signal sent to the unit is linearly converted using a -5K to +5K range of temperature set point.
For example: for a unit set point of 20°C
A 4mA signal will give a 15°C unit temperature set point
A 12mA signal will give a 20°C unit temperature set point
A 20mA signal will give a 25°C unit temperature set point
Minimum Fresh Air Set Point – 4-20mA Signal:
The 4-20mA signal sent to the unit is linearly converted to a 0% - 100% fresh air damper opening request.
Entry for a Meteorological Temperature Sensor:
The 4-20mA signal sent to the unit is linearly converted using a -40°C to +80°C range, this measure will replace the one
given by the unit sensor.
Input for a Meteorological Sensor for Relative Humidity:
The 4-20mA signal sent to the unit is linearly converted using a 0% to 100% range, this measure will replace the one given
by the unit sensor.
Free Temperature Probe Connection:
Lennox NTC sensor.
Free Relative Humidity Sensor Connection:
The 4-20mA signal sent to the unit is linearly converted using a 0% to 100% range.
