DESCRIPTION OF THE DIP SWITCH FUNCTIONS
DIP Switch 1 : GE/HP Operation
Place DIP Switch 1 to OFF position for Gas/Electric furnace
operation.
Place DIP Switch 1 to ON position for Heat Pump operation.
DIP Switch 2 : CLK Terminal Operation
Place DIP Switch 2 to OFF position t o allow a short across the
CLK terminals via contact closure or Robertshaw® Occupancy
Sensor to engage Night (Schedule 4) operation until released.
Place DIP Switch 2 to ON position to allow a short to change the
thermostat to OFF mode until released.
DIP Switch 3 : 2 Minute or 4 Minute Minimum Off Times
When DIP Switch 3 is in the ON position, the minimum OFF time
is 2 minutes. When in the OFF position it is set to 4 minutes. The
system will 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(2°C) or +/-5°F(3°C) range from
the current or last occupied setpoints as defined by DIP Switch
7. Users will still be able to alternate 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.
Place DIP Switch 5 to OFF and DIP Switch 1 to OFF to have the
fan turn on immediately when there is a call for heat. (Required
with electric heat.)
Place DIP Switch 5 to ON and DIP Switch 1 to OFF to have the
plenum switch operate the fan.
Place DIP Switch 5 to OFF and DIP Switch 1 to ON for normal
heat pump operation.
Place DIP Switch 5 to ON and DIP Switch 1 to ON for Add-On
(Dual-Fuel) Heat Pump operation.
DIP Switch 6 : OFF
Keep OFF
DIP Switch 7 : Temporary Override Adjustment Range
Place DIP Switch 7 to OFF to limit temporary adjustments to
+/-3°F(2°C).
Place DIP Switch 7 to ON limit temporary adjustments to
+/-5°F(3°C) .
DIP Switch 8 : Remote Sensor Operation
(For Non-Programmable Operation Only)
Place DIP Switch 8 to OFF to only use the remote indoor sensor
(10-528 or RS300-528) for temperature control.
Place DIP Switch 8 to ON to average the thermostat's internal
sensor with the remote indoor sensor(s).
NOTE: If no remote sensor is used, the thermostat will default to
the thermostat sensor regardless of the DIP Switch setting.
NOTE: For 7 Day and 5-1-1 Day programmable operation, the
remote sensor operation is determined in the schedule
programming, allowing each schedule to use the Internal,
Remote or Average of the sensors. See RS300P Schedule
Programming Document for full details.

FEATURES AND SETTINGS
LED #1 (GREEN): Filter Indicator
This LED will illuminate when a signal is received from Terminal
LED1 on the Terminal block. The Green (left) LED at the top of
the thermostat and if selected by the software, the FILTER icon in
the display will turn on, indicating the filter needs to be changed.
LED #2 (YELLOW): Service Indicator
This LED will illuminate when a signal is received from Terminal
LED2 on the Terminal block. This terminal is usually connected to
the L terminal on a Heat Pump. When a signal is received, the
yellow (right) LED at the top of the thermostat will turn on and if
selected by the software, the WRENCH icon in the display will
turn on, indicating service is required.
LED #3 (RED): Auxiliary/Emergency Heat Indicator
(no associated screw terminal)
The thermostat is equipped with an LED that indicates when the
system has engaged auxiliary heat mode or emergency heat
mode. It is the red (center) LED.
RS1 – RS2 – RS+V: Remote Sensor Bus
Used for connection of a wide variety of Robertshaw® remote
sensors, allowing installation flexibility and additional information
from the communications bus. It also allows the thermostat to be
placed in an area away from view.
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 Robertshaw®
RS300P 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 Configuration
If the thermostat is being used as a Heat Pump thermostat (DIP
Switch #1 in the ON position and an outdoor sensor (10-529 or
RS300-529) is connected to the remote sensor terminals, the
thermostat can be configured 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, use the
integrated setup menu or:
1. Press RESUME & VACATION together to show 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:
See heat pump manual for temp cut-offs
specifications.

FEATURES AND SETTINGS, continued
Override Timer Configuration
The length of a temporary override can be adjusted from 0
minutes to 24 hours, in 10 minute increments. (0 minutes is a
complete lockout). The default override time is 8 hours. To
display/set the Override time, either use the integrated setup
menu or press the MODE and VACATION buttons
simultaneously, then press the UP or DOWN button.
Recirculation Fan Configuration
Using the Setup Menu, Recirculation Fan can be set for up to 30
minutes of fan operation per hour. Default is 0 min.
Fan Purge Configuration
Using the Setup Menu, Fan Purge time can be set for up to 60
seconds of fan run after a heating or cooling call in order to
release remaining conditioned air into the space. Default is 0 sec.
Temperature Calibration (De-calibration)
The thermostat is pre-calibrated at the factory, but in some
installations, lack of airflow at the sensor or proximity to other
warming or cooling source may cause the temperature to be off
by a few degrees. To adjust the room temperature reading (with
or without a remote indoor sensor connected), press and hold
the Fan button for 12 seconds. The display will then show the
room temp with 0.06F degree resolution. Press the UP or
DOWN button to make the adjustment. Press the RESUME
button to store the new value. To restore the thermostat to
factory calibration, while in calibration mode, press the MODE
button to reset and then the RESUME button to store.
Deadband Configuration
Using the Setup Menu, when in Auto Mode the minimum
difference between heating and cooling setpoints can be adjusted
from 2°F(1°C) to 8°F(4°C). The default is 2°F(1°C).
Schedule Programming
See the separate document RS300P Schedule Programming for
complete scheduling details.
COVER LOCK
You also may lock the cover down to prevent unauthorized
access 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.
