Setup Menu
The Setup Menu page is accessed by pressing and holding the OK
button for one second while on the Main page. Item 1) in the Setup
Menu changes depending on which mode is selected and will al-
ways match the Mode listed in item 4 (Figure 10).
Flow Configuration / Minimum Pump Speed %
The Flow Configuration menu (Figure 11) is accessed by selecting 1)
FLOW from the Setup Menu when item 4) is set to FLOW. Separate
flow rates for Stage 1 and Stage 2 operation can be specified. The
flow rate specified for STAGE 1 will be applied when the control-
ler receives a 24 VAC signal at the left HP IN1 terminal, or when a
dry contact is made across the two HP IN1 terminals. The flow rate
specified for STAGE 2 will be applied when the controller receives
a 24 VAC signal at the left HP IN2 terminal, or when a dry contact
is made across the two HP IN2 terminals. Press the OK button to
select Item 1) STAGE 1 or Item 2) STAGE 2 and the +/- buttons to set
the values.
Item 3) MIN% in the Flow Configuration menu allows for a mini-
mum pump speed percentage set point. Although not typically
used for residential applications, the pump speed may be set to
remain above a certain percentage RPM regardless of the flow rate
setting for STAGE 1. To change minimum %, press the arrow down
(-) button to select item 3). Press the OK button to select the MIN
% menu (the triangle cursor will turn solid), and use the +/- buttons
to set the value. Once set, press the OK button again to lock in the
value.
NOTE: If system status display shows
pump(s) running, but heat pump is
not operating, check wiring vs. dia-
gram on pages 5 to 7. Isolation may
be required between ACC/Y2 and the
controller.
