UPM Dip Switch Settings
The DIP switches are used to configure most of the available fea
-
tures of the UPM as follows:
• Lockout mode: two (2) or four (4) strikes
• Reset mode: Y signal or R signal
• Alarm mode: Constant or Pulse
• Test mode: Normal or Test operation
Figure 36 shows the factory default settings for most heat
pump applications. However, the unit wiring diagram is the ul
-
timate guide for factory DIP switch default settings. See the
Unit Protection Module section in the Troubleshooting section
for further details.

Typical DIP Switch Factory Defaults
Table 10 below shows the available options on the UPM board
DIP switch banks.

UPM DIP Switch Options
Alarm Output
Alarm output is normally open (NO) dry contact. If pulse is select
-
ed the alarm output will be pulsed. The fault output will depend on
the DIP switch setting for ALARM. If it is set to CONST, a con
-
stant signal will be produced to indicate a fault has occurred and
the unit requires inspection to determine the type of fault. If it is
set to PULSE, a pulse signal is produced and a fault code is detect
-
ed by a remote device indicating the fault. The remote device must
have a malfunction detection capability when the UPM board is
set to PULSE.
WATERSIDE ECONOMIZER (ETO)
When the waterside economizer option is built with the Complete
C or Deluxe D controls, it will include an aquastat for economizer
control. The aquastat can be adjusted between 20°F and 60°F.
When the water loop temperature is below the aquastat set point,
the economizer is enabled. The recommended aquastat set point is
55°F. See Fig. 37.
BOILERLESS HEAT CONTROL (DELUXE D ONLY)
All units with Deluxe D control include an aquastat for boilerless
heat control. The aquastat can be adjusted between 20°F and 60°F.
When the water loop temperature is below the aquastat set point,
the heat pump heating is disabled and a field provided auxiliary
heat can be enabled. The recommended aquastat set point is 55°F.
See Fig. 37.

CAUTION
Operation of unit in test mode can lead to accelerated wear and
premature failure of components. The "TEST" switch must be
set back to "NO" after troubleshooting/servicing.
IMPORTANT: If 24 VAC output is needed R must be wired to
ALR-COM terminal; 24 VAC will be available to the
ALR-OUT terminal when the unit is in the alarm condition.
