KEYPAD LOCKOUT
When DIP Switch #4 is ON, the keypad is locked and temporary
adjustment to the setpoints are restricted to a setpoint range of
+/-3°F(2°C) or +/-5°F(3°C) from the current or last occupied
schedule setpoints for the amount of time set in the override
timer.
TEMPORARY OVERRIDE
(in KEYPAD LOCKOUT MODE)
Change the temperature setting temporarily without affecting the
schedule setpoints, even though the keypad is locked.
Press the UP or DOWN button. If running in an occupied
schedule, the current occupied schedule setpoint will be
shown, and if running in an unoccupied schedule, the current
unoccupied schedule setpoint will be shown.
Press the UP or DOWN button again. If an occupied
schedule is running, then the current occupied setpoint will be
shown and an override will be started. If an unoccupied
schedule is running, then the most recent occupied setpoint
will be shown and an override will be started. If in AUTO
mode, press the MODE button to switch between heating and
cooling setpoints.
Press the UP or DOWN button again to adjust the
temperature up to the maximum of +/-3°F(2°C) or +/-5°F(3°C)
for the duration of the override time.
To cancel, simply press the RESUME button.

SETBACK INPUT TERMINALS
The CLK terminals allow for two powerful methods to operate the
thermostat in special conditions when an external stimulus is used
to short the CLK1/CLK2 terminals. This allows an external time
clock or other external relay, or a Robertshaw® Occupancy
Sensor (RS-OSC or RS-OSW) to be incorporated into the control.
Setback with No Override
With DIP Switch 2 in the OFF position, DIP Switch 4 in the
ON position (Keypad Locked), and then the CLK terminals are
shorted, the thermostat will lock into Night (Schedule 4)
operation (and setpoints) as long as the terminals are
shorted. Programmed Schedule changes will be ignored until
the short is removed.
Setback with Override
With DIP Switch 2 in the OFF position, DIP Switch 4 in the
OFF position (Keypad Unlocked), and then the CLK terminals
are shorted, the thermostat will go into Night (Schedule 4)
operation (and setpoints) as long as the terminals are
shorted. Most keypad presses and will be ignored until the
short is removed, but an override to the last Occupied
Schedule setpoints can be achieved by pressing the UP or
DOWN buttons. The override will last as long as the override
timer. See 'TEMPORARY OVERRIDE'. When the short is
removed, the thermostat will return to its Night (Schedule 4)
setpoints.
Set Mode to OFF with CLK Terminals
When DIP Switch 2 is in the ON position and the CLK
terminals are shorted, the thermostat will change to OFF
mode and only the FAN button can be used until the short is
rd
removed. This feature allows a 3
party set of contacts (such
as door or window sensors) to be connected to the CLK
terminals to shut down the HVAC equipment when a door or
window is open. The installer is responsible for any
necessary time delay to be added to the contacts as needed
to perform the desired function. When the short is removed,
the thermostat will revert to its previous operation.
CHANGING FAHRENHEIT (°F) TO CELSIUS (°C)
To change between °F and °C, use the integrated set up menu or
simultaneously press the UP and DOWN buttons. The display will
change automatically.

POWER FAILURES
This Robertshaw® thermostat product will maintain the operation
settings during any type of power failure and contains a special
circuit to retain the time/day for about 30 minutes without power. If
power is restored with the time/day still available, the
thermostat will return to the last operation or schedule. If the
clock is not available, the thermostat will run as a 'manual'
thermostat until the clock is set. If the CLK terminals are shorted
at power up, the thermostat will operate using the last NIGHT
(Schedule 4) setpoints.
REMOTE SENSORS (OPTIONAL)
If your Robertshaw® thermostat has been installed with one or
more Robertshaw® remote sensors, the sensor information is
available on the small secondary display of the thermostat. There
are many different remote sensors. The robertshawclimate.com
website shows detailed information. You can view the remote
sensor information by simply pressing and holding the RESUME
and VACATION buttons simultaneously, and then use the UP or
DOWN button to view the various sensors.

SETUP MENU
The RS300P family of thermostats has a powerful Integrated
Setup Menu, allowing quick access to the following setup
functions. To access the menu, simultaneously press and Hold
the UP and DOWN buttons for two (2) seconds. When the
display changes, use the UP or DOWN buttons to select the
option needed, the MODE button to go to the next setup function,
and the RESUME button to save and exit. If there are no
additional button presses for 15 seconds, the thermostat will
store, exit and return to normal operation. All settings are stored
