Dipswitches - Rheem *96V series Installation Instructions Manual

DIPSWITCHES

2. For communicating systems, dipswitches are not
used. Configuration changes are made with the
thermostat.
A. Seven-Segment Display Orientation; S1-1
As the control will be applied in a multi-position fur-
nace a means of changing the orientation of the
seven segment display is provided. This dipswitch
is to be labeled S1-1. Factory setting of the S1-1
dipswitch is OFF.
S1-1 = OFF = Upflow (as-shipped) position
S1-1 = ON = Downflow position
B. Cool Blower-Off Delay; S1-2 & S1-3
A means of selecting the cooling speed blower "off"
delay time is provided. In legacy mode, dip-
switches are required to select the delay time.
These dipswitches are to be labeled S1-2 and S1-
3. The following table defines the settings:
S1-2 SW3
OFF OFF
Note: Factory setting = 30 seconds
ON OFF
OFF ON
ON ON
C. Cooling Airflow Selection; S1-4 & S1-5
S1-4 and S1-5 are to be used to select cooling air-
flow in legacy mode. The value used for each se-
lection is specified below.
HIGH COOL SELECTIONS:
½ HP Blower
S1-4 S1-5 (42, 56 &
70 KBTU)
OFF OFF 1050 CFM
ON OFF 875 CFM
OFF ON 700 CFM
ON ON 525 CFM
LOW COOL SELECTIONS:
The following model data fields are multipliers to be used
for low stage legacy cooling unless dipswitch S2-9 is in
the ON position - in which case the low cooling airflow be-
comes 50% of the high cooling airflow.

Airflow dipswitches are to be used to determine airflow
when a legacy (24 VAC) call is placed on the thermostat
inputs of the control. Communicated calls will have CFM
requirements as part of the call (when a legacy condenser
is attached to a communicating furnace the airflow de-
mand will be transmitted from the communicating thermo-
stat as the installer will configure the cooling airflow
requirements for the non-communicating condenser at the
thermostat and the airflow requirements for the condenser
will be stored at and transmitted from the thermostat).
D. Cooling/Heat Pump Airflow Trim; S1-6 & S2-7
Two dipswitches (S1-6, S2-7) are to be provided
for legacy cool airflow trim. The value used for
each selection is specified below. Two of these val-
ues are taken from the furnace Model Data file.
Selections are as follows:
S1-6 S2-7 Description
OFF OFF No Adjust. (Factory Setting)
ON OFF +10%
OFF ON -10%
ON ON No Adjust.
E. ODD (On Demand Dehumidification); S2-8
One dipswitch (S2-8) is to be provided to enable
the dehumidification feature in legacy mode. Se-
lections are as follows:
S2-8=OFF ODD not enabled.
(Factory Setting)
S2-8=ON ODD enabled. 0VAC on
"HUM STAT" will decrease
airflow in cooling.
F. Tandem Airflow Select; S2-9
One dipswitch (S2-9) shall be used to select the
percentage of airflow for the base first stage cool-
ing airflow in legacy mode. Note that further ad-
justments may also be applied (e.g. for active
dehumidification or cooling airflow trim).
