Robertshaw 9200 Bedienungsanleitung
WARNING: THIS THERMOSTAT MUST BE INSTALLED ONLY BY A PROFESSIONAL CONTRAC-
TOR FAMILIAR WITH AIR CONDITIONING AND HEATING SYSTEMS CONTROLS AND WIRING.
INSTALL ONLY ON 24V AC SYSTEMS. PLEASE READ THIS MANUAL CAREFULLY BEFORE
INSTALLING.
IMPORTANT SAFETY INFORMATION
WARNING:
• Always turn off power at the main power source by unscrewing the fuse
or switching the circuit breaker to the off position before installing,
removing, cleaning or servicing thermostat.
• Read all of the information in this manual before installing this thermostat.
• This is a 24V AC low-voltage thermostat. Do not install on voltages higher
than 30V AC.
• All wiring must conform to local and national building and electrical
codes and ordinances.
• Do not short (jumper) across terminals on the gas valve or at the system
control to test installation. This will damage the thermostat and void the
warranty.
FEATURES
• Adjustable from 50°F (10°C) to 90°F (32°C)
• Accuracy within ± 2 degrees Fahrenheit
• Heavy duty heat anticipator
• Hermetically sealed contacts
• No separate subbase

REPLACING EXISTING THERMOSTAT
1. Turn off power to heating and cooling system.
2. Remove cover of old thermostat to expose wires. Do not disconnect
wires. (Figure 1)
3. Label wires per Table 1.
TABLE 1
Old Label New label** Description
M, 4, RH, R5 or R RH Heat transformer, hot side
V or RC RC Cooling transformer, hot side
Y or Y6 Y Cooling control
H, W or 4 W Heating control
F or G G Fan control relay
B B Reversing valve heating mode
O O Reversing valve cooling mode
*NOTE: ON SOME OLDER MODELS, THE C TERMINAL CAN BE EITHER THE COOLING CON-
TROL OR THE COMMON SIDE OF THE TRANSFORMER. CHECK FURNACE WIRING DIAGRAM TO
VERIFY C TERMINAL. IF IT IS THE COMMON SIDE OF THE TRANSFORMER, CAP THE WIRE AND
TUCK INTO THE WALL. IF IT IS THE COOLING CONTROL, CONNECT TO THE Y TERMINAL.
**NOT ALL MODELS OF THE 9200 SERIES WILL CARRY THESE DESIGNATIONS.
4. After labeling wires, remove wires from terminals.
5. Remove existing thermostat base from wall.
6. Refer to the following section for instructions on how to install thermostat.

INSTALLING MODEL 9200 THERMOSTAT
NOTE: FOR NEW INSTALLATIONS, MOUNT THERMOSTAT ON INSIDE WALL, 5 FEET ABOVE
THE FLOOR. DO NOT INSTALL BEHIND A DOOR, IN A CORNER, NEAR AIR VENTS, IN
DIRECT SUNLIGHT, OR NEAR ANY HEAT OR STEAM GENERATING FIXTURES. INSTALLATION
AT THESE PLACES WILL AFFECT THERMOSTAT OPERATION.
1. Turn power off to the heating and cooling systems.
2. Remove cover by grasping side and
gently pulling outward (Figure 2).
3. Place thermostat against the wall at
desired location. Make sure wires will
feed through opening on base of thermo-
stat.
4. Mark placement of mounting holes
(Figure 3). Set base aside.
5. Drill the marked holes using a 3/16” drill bit.
6. Tap plastic anchors into the holes.
7. Align base with plastic anchors and feed wires through opening.
8. Secure base to wall with supplied screws.
9. Connect wires to proper terminal screws. Refer to wiring diagrams
on other side of this sheet. Make sure wire connections are secure.
10. Set the adjustable heat anticipator as outlined in the next section
SETTING HEAT ANTICIPATOR. For millivolt applications, set anticipa-
tor to highest setting.
11. Place fan option jumper plug to G (gas) or E (electric) position
depending on heating system.
12. Replace cover on thermostat by snapping into place.
13. Turn on power to system. Test thermostat as described in the
following section.
HEAT PUMP APPLICATIONS
For single stage heat pump applications (no auxiliary or emergency heat),
install a short jumper across W and Y terminals and make sure the jumper
plug is in the E position.
Connect the reversing valve wire to the O terminal if the reversing valve is
energized in the cooling mode. If the reversing valve is energized in the
heating mode, connect the wire to the B terminal.
DUAL TRANSFORMER APPLICATIONS
When two transformers are being used, remove the factory installed
jumper between Rh and Rc.

OTHER APPLICATIONS
To power a damper motor or auxiliary circuit that requires continuous
power, O and B terminals are provided. (For example, the damper needs to
be opened whenever the thermostat is being used for cooling.) When the
system switch is in the cool position, the O terminal is energized.
SETTING HEAT ANTICIPATOR
NOTE: SOME HEATING SYSTEMS REQUIRE A LONGER OR SHORTER ON/OFF PERIOD
TO MAINTAIN COMFORT. SET THE HEAT ANTICIPATOR TO ONE OF THE FOLLOWING
CONDITIONS. (REFER TO FIGURE 4)
1. For replacement installations, match the anticipator setting with that
of the thermostat being replaced.
OR
2. Match current draw (amperage) of the heating control or relay. This
can be done by checking the rating label on the control within the
heating system. If the label cannot be found, the circuit amperage
can be determined as follows:
a. Turn HEAT-OFF-COOL switch to OFF, or set temperature to lowest
setting so that the contacts are open.
b. Set an AC ammeter to the 0 to 1 amperage
range. Place probes on W and R terminals.
On heating only models probe both wires.
On models with a positive off lever, make
sure the lever is in the OFF position. The
heating valve or relay must then turn ON
and a reading will appear on the meter. DO
NOT USE A VOLTMETER OR A DC AMME-
TER.
c. Set the heat anticipator to the meter
reading. This is the normal setting.
3. The anticipator adjustment must be made so that the thermostat is in
balance with the rest of the system. It will determine how often the
system turns on and off.
Allow the heating system to operate for a full day or more. A correct
anticipator setting should maintain the temperature within 1°F. Too
frequent cycling of the heating system can result in lower life
expectancy for the heating system. Make anticipator adjustments in
0.1 amp increments at a time.
WARNING: THE ADJUSTABLE HEAT ANTICIPATOR WILL BURN OUT IF 25V ARE APPLIED
DIRECTLY TO THE THERMOSTAT BY SHORTING OUT THE GAS VALVE OR PRIMARY CONTROL
DURING TESTING OR BY INCORRECT WIRING.
NOTE: FOR MILLIVOLT HEATING APPLICATIONS (9204H AND 9204V ONLY) THE
ANTICIPATOR MUST BE SET TO ITS HIGHEST LEVEL.
TO TEST THERMOSTAT
WARNING: DO NOT SHORT (JUMPER) ACROSS TERMINALS OF GAS
VALVE OR SYSTEM CONTROL TO TEST OPERATION. THIS WILL DAMAGE
THE THERMOSTAT AND VOID YOUR WARRANTY.
CAUTION: DO NOT SWITCH SYSTEM TO COOL IF THE TEMPERATURE IS BELOW
50°F (10°C). THIS CAN DAMAGE THE AIR CONDITIONING SYSTEM AND CAUSE
PERSONAL INJURY.

1. Place the HEAT-OFF-COOL
switch into the COOL position
2. Adjust the temperature lever until the indicator is at least 3° below
the room temperature. The air conditioning system should turn on
within a few seconds.
3. Put the HEAT-OFF-COOL switch into the OFF
position. The air conditioning system
should turn off.
WARNING: DO NOT PLACE THE HEAT/OFF/COOL SWITCH BACK INTO THE
COOL MODE. QUICK REPETITIVE CYCLES OF THE AIR CONDITIONING SYSTEM CAN LEAD
TO A LOWER LIFE EXPECTANCY FOR THE COMPRESSOR.
4. Put the HEAT-OFF-COOL
switch into the HEAT position.
5. Adjust the temperature lever until the indicator is at least 3° above
the room temperature. The heating system should turn on within a
few seconds.
6. Put the HEAT-OFF-COOL switch into the OFF
position. The heating system should turn off.
The fan may continue to run for a short peri-
od of time.
7. Put the FAN AUTO-ON
switch to the ON position.
The blower fan should turn on.
8. Put the FAN AUTO-ON
switch to the AUTO position.
The blower fan should turn off.
