(Future Availability on Select Models/Configurations)
1.
Accessory Relay2 – A second, configurable, accessory
relay on the AXB is provided that can be cycled with
the compressor 1 or 2 , blower, or the Dehumidifier (DH)
input. This is to complement the Accessory 1 Relay on
the ABC board.

Analog Out – A standard 0-10VDC analog output is
provided. This output can be used to drive modulat-
ing dampers etc.
3.
Variable Speed Pump or Modulating Water Valve
(If applicable) - This input and output are provided
to drive and monitor a variable speed pump. The VS
pump output is a PWM signal to drive the variable
speed pump. The minimum and maximum level are set
using the AID Tool. 75% and 100% are the default set-
tings respectively. The VS data input allows a separate
PWM signal to return from the pump giving fault and
performance information. Fault received from the vari-
able speed pump will be displayed as E16. Modulat-
ing Water Valve - This Variable speed PWM output is
provided to optionally drive a modulating water valve.
Through advanced design a 0-10VDC valve can be
driven directly from the VS pump output. The mini-
mum and maximum level are set in the same way as
the VS pump using the AID Tool. 75% and 100% are
the default settings respectively.
4.
Loop Pump Slaving (If applicable) - This input and
output are provided so that two units can be slaved
together with a common flow center. When either unit
has a call for loop pump, both unit's loop pump relays
and variable speed pumps are energized. The flow
center then can simply be wired to either unit. The
output from one unit should be routed to the input of
the other. If daisy chained up to 16 heat pumps can be
wired and slaved together in this fashion.
