13. Attach display module body to equipment control module
by first setting the module on at top of equipment control
module and then snapping the bottom corners of display
module into place.
14. Turn on power to equipment. On power up, all display
segments will light for 5 seconds. For the next 5 seconds,
a 2-digit code will appear on the center of the large dis-
play which identifies the equipment configuration:
AC — Two-stage heat / Two-stage cool
HP — Three-stage heat / Two-stage cool
The thermostat is powered by 24 vac only. The
Power —
thermostat requires the 24 vac (Rh and/or Rc and C terminals)
of the low-voltage transformer to be connected to it for proper
operation. The thermostat will not operate without these
connections. The Rh and Rc terminals are connected via the
PCB breakout jumper. For applications using a single 24-vac
transformer for power, the breakout jumper should remain
intact. For applications using two 24-vac transformers, the
breakout jumper must be broken because possible voltage
differences between the two transformers could cause irregular
operation or damage to the thermostat. See Fig. 12.
For applications using two 24-vac transformers, one in the
indoor unit and one in the outdoor unit, connect the common
wire from each to the C terminal. Connect R from the indoor
unit to the Rh terminal. Connect R from the outdoor unit to the
Rc terminal. Break the jumper on the circuit board. See Fig. 12.
The W and HUM signals are taken from the Rh power and the
G signal is taken from the Rc power.
If the control has been installed in a two-transformer appli-
cation that is later changed to a single-transformer installation,
the installer must install a field-supplied jumper between Rc
and Rh. Depending on the installation, up to 14 wires may be
required. Installation as two-piece unit is recommended. Only
two wires are required for connection between display module
and equipment control module. These two wires (V+ and Vg)
do not provide ordinary 24 vac. They carry a combination of
power and communications data that is unique to these
products.

Humidification Equipment and Connections
(33CS2PPRH-03 Model Only) —
output connects directly to 24-vac operated humidifiers. No
other connection or interlock is required. Any of several
installer-selectable operating modes are available.
WARNING
DO NOT connect unit HUM terminal directly to thermo-
stat control HUM terminal. This will bypass unit safety
controls. Personal injury or death could result.
Dehumidification Equipment and Connec-
The D1 and D2 terminals are for a dry relay con-
tions —
tact. Operating the relay by itself will not cause 24 V to appear
at the terminal. To have 24 V appear at D2, D1 has to have a
wire jumper added to either Rc or Rh.
The dry contact must be configured for dehumidification in
configuration Option 19. See page 8. See Wiring Diagrams for
more information.

CONFIGURATION

To Enter and Exit Configuration Mode —
and hold OCCUPIED button for approximately 10 seconds.
The display module will now be in Configuration mode. The
module will automatically exit this mode if no button is pressed
for 3 minutes. Pressing the DONE button will exit Configura-
tion mode immediately.
Configuration Mode —
played in the heat set point location and the configuration set-
ting is displayed in the cool set point location. A box will sur-
round the option number. The MODE button is used to move
the box between the two displayed values or the soft keys be-
low the values may also be used. The value inside the box is
changed by using the UP and DOWN buttons. All changes
made are saved at the time of selection and will be saved in the
event of the 3-minute timeout or when installer exits from con-
figuration menu. See Table 1.
