Network Thermostat RP32-NX Technical specifications

REMOVING THE THERMOSTAT FROM
THE BACKPLATE
1. Insert a at blade screwdriver or coin 1/8” into the slot located
in the bottom center of the thermostat case and twist 1/4 turn.
When you feel or hear a click, grasp the case from the bottom
two corners and separate from the backplate as shown in the
diagram at the left. Some models require more force than
others when separating due to the number of terminals used.
2. Swing the thermostat out from the bottom.
3. Lift the thermostat up and off the backplate.
4. Place the rectangular opening in the backplate over the
equipment control wires protruding from the wall and, using
the backplate as a template, mark the location of the two
mounting holes. NOTE: If adding the wireless backplate
(WBM-1 or WBM-WiFi), simply discard the backplate which
came with the thermostat. The wiring instructions for the
equipment are identical.
5. Use the supplied anchors and screws for mounting on drywall
or plaster; drill two 3/16” (5mm) diameter holes at the marked
locations; use a hammer to tap the nylon anchors in ush
to the wall surface and fasten backplate using the supplied
screws. (Do not over tighten!)
6. Connect the wires from your system to the thermostat
terminals as shown in the wiring diagrams. Carefully dress
the wires so that any excess is pushed back into the wall
cavity or junction box. Ensure that the wires are ush to the
plastic backplate. The access hole should be sealed or
stuffed to prevent drafts from affecting the thermostat.
BUTTON OPERATION
THERMOSTAT LOCATION
To ensure proper operation, the thermostat should be mounted
on an inside wall in a frequently occupied area of the space.
In addition, its position must be at least 18” (46 cm) from any
outside wall, and approximately 5’, (1.5 m) above the oor in a
location with freely circulating air of an average temperature.
Be sure to avoid the following locations:
• Behind doors or in corners where freely circulating air is
unavailable
• Where direct sunlight or radiant heat from appliances might
affect control operation
• On an outside wall
• Adjacent to, or in line with, conditioned air discharge grilles,
stairwells or outside doors
• Where its operation may be affected by steam or water pipes
or warm air stacks in an adjacent partition, or by an unheated/
uncooled area behind the thermostat
• Where its operation may be affected by lighting dimmers
next to it
• Where its operation will be affected by the supply air of an
adjacent unit
• Near sources of electrical interference such as arcing
relay contact

condition from 15 minutes to 8 hours, in 15 minute increments.
To display/set the Override time, press and hold the FAN and
VACATION buttons for 12 seconds, then press the UP or DOWN
button. Future ‘overrides’ to the schedule will hold the setpoint
for the desired time and then return to the pre-programmed
schedule.
COVER LOCK
You also may lock the cover down to prevent unauthorized ac-
cess to the thermostat by adding the clear plastic lock (included
in the installation bag). To install, remove the thermostat from
the backplate and place the clear plastic lock in the backplate
as shown below. Replace the thermostat and close the cover.
The cover now is locked. To open, simply use a screwdriver
to carefully push the lock back, allowing the cover to open. To
remove the lock, open the cover, remove the thermostat from the
backplate, and then remove the lock.
REPLACING THE THERMOSTAT ON
THE BACKPLATE
1. Position the thermostat on the hinged tabs located at the top
of the backplate.
2. Gently swing the thermostat down and press on the bottom
center edge until it snaps in place.
FEATURES AND SETTINGS
LED #1 (GREEN): Filter Indicator
The green (left) LED may be used together with the FILTER icon
to indicate the HVAC system’s air lter(s) need to be changed.
LED #2 (YELLOW): Service Indicator
The yellow (right) LED may be used together with the WRENCH
icon to indicate there is a problem with the HVAC system.
LED #3 (RED): Auxiliary/Emergency Heat Indicator
The red (center) LED will illuminate when the thermostat has
engaged a heat pump system into either auxiliary heat mode or
emergency heat mode.
Note: The green, yellow and red LEDs may also be used to
indicate Off-Peak, Mid-Peak and On-Peak time of use (TOU)
energy rate pricing plans as dened by your electric utility
provider. This feature is only available when the thermostat is
connected via communications to your utility company’s network.
While NetworkThermostat has included these LEDs to be
accessible by utility companies, use of this feature may require
upgraded rmware or communications hardware, yet to be
dened by NetworkThermostat or your utility company.
Add-On (Dual-Fuel) Heat Pump Control
If needed, the thermostat will perform the function of a fossil
fuel kit. When in this mode, the thermostat will turn off the
compressor with a call for AUX heat. When Switch 1 and
Switch 5 are in the ON position, the thermostat allows the
compressor and the AUX heat to be on simultaneously.
Random Restart
After a power failure, the thermostat will delay the heating/
cooling equipment start-up by 8-40 seconds. When multiple
Net/X™ RP32-NX thermostats are used, this minimizes the ‘in
rush’ current (electric power usage) as it reduces the number of
HVAC units that will be turned on simultaneously.
High & Low Balance Point Conguration
If the thermostat is being used as a Heat Pump thermostat
(Dip Switch #1 in the ON position), and outdoor temperature
information is available by using an Internet connection, the
thermostat can be congured to disable the use of auxiliary
heat during warmer weather and to lock out the compressor
during colder weather.
To display/set the High and Low balance points:
1. Press RESUME and VACATION together to show the outdoor
temperature.
2. Press and hold the MODE and RESUME buttons for 5 seconds
to evoke the High and Low balance point temperatures.
The display will indicate the high or low balance point and the
selected temperature. Press the UP or DOWN button to adjust
the balance point temperature. Pressing the MODE button again
will toggle to the alternate balance point.
NOTE: Refer to the heat pump equipment manual for
temperature cut-offs on the equipment.
DESCRIPTION OF THE DIP SWITCH FUNCTIONS
DIP Switch 1: GE/HP Operation
Place DIP Switch 1 in the OFF position for Gas/Electric furnace
operation.
Place DIP Switch 1 in the ON position for Heat Pump operation.
DIP Switch 2: Adaptive Setpoint Recovery
Place DIP Switch 2 in the OFF position for Adaptive Setpoint
Recovery operation. When this is enabled, the thermostat will
anticipate when to turn on the heating or cooling system prior to
the start of a schedule in order to achieve the desired setpoint
temperature by the beginning of the schedule.
DIP Switch 3: 2 Minute or 4 Minute Minimum On/Off Times
When DIP Switch 3 is in the ON position, the minimum ON/OFF
time is 2 minutes. The system will operate for a minimum of 2
minutes or 4 minutes, and allow equipment recovery for 2 or 4
minutes before turning on again. This is also known as short
cycle protection.
DIP Switch 4: Unlocked/Locked Keypad
When DIP Switch 4 is in the ON position, all buttons are disabled
with the exception of the UP, DOWN and MODE button. Users
will be restricted to either a +/-3°F or +/-5°F range from the
scheduled setpoints as dened by Dip Switch #7 for the
programmed override time. Users will still be able to cycle
between HEAT and COOL.
DIP Switch 5: Plenum Fan Switch /Add-On Heat Pump
DIP Switch 5 is used to determine when the fan needs to be
turned on.

DESCRIPTION OF ICONS
SENSOR FAULTS
There are two sensor faults:
1. Internal sensor is shorted.
2. Internal sensor is open.
When the internal sensor is shorted [the sensed temperature
>= 124°F (48°C)], all equipment is turned off and the following
icons are ashed on the LCD:
When the internal sensor is open [the sensed temperature
<= 32°F (0°C)], all equipment is turned off and the following icons
are ashed on the LCD:
An open condition is ignored the rst 20 minutes after powering
the thermostat to allow the equipment to heat the surrounding
environment. This will avoid premature deactivation of the
equipment if the ambient temperature should happen to be
below 32°F (0°C).
