Communication :
Terminal's X5 & X6 configurable as RS485 MODBUS Outputs
X7 can be set to ground
(via a 100 ohm resistor)
for use as a
comms shield connection if not used as a CO2 sensor connection.
ANALOG INPUTS
X1
:
Main Temperature Sensor Input configurable (with jumper & software) as
Active (0-10vdc ~0 to 100c (adjustable) or Passive (4.2k@22c).
X2 : Remote Set point configurable (with jumper & software) as passive using 10K
Potentiometer (18-25c Range) or 0-10vdc (top end range configurable).
X3 : Outside temperature sensor configurable (with jumper & software) as Active
(0-10v~0-100c) or Passive (4.2k@22c).
X4 : Auxiliary Measurement Temperature Sensor, Input configurable (with jumper)
as Active (0-10vdc ~0 to 100c (adjustable) or Passive (4.2k@22c).
X7 : Room or R/A Duct CO2 Sensor input to override economy cycle operation or
to control internal relays (R1-4) not used for temperature control.
