Robertshaw RS9210 Programmable Thermostat

Thank you for purchasing a Robertshaw® thermostat. This manual will describe how to install and test the Robertshaw RS9210 thermostat.

Thermostat System Types

Gas, Oil, or Electric Heat with Air Conditioning

Heat Pumps (with or without auxiliary or emergency heat)

Multi-Stage Systems

Heat-Only, including for Floor and Wall-Furnace

Cool-Only

750 Millivolt Heating Systems

Power Options

• Battery Power
• Hardwire (Common Wire)

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 the thermostat.
• Read all of the information in this manual before installing or programming 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.

INSTALLATION LOCATION

Install the thermostat 4 to 5 feet above the floor in an area with good air circulation and average temperature. For new installations, mount the thermostat on an inside wall, 4-5 feet above the floor. Do not install the thermostat in the following locations:

• Behind a Door
• In a Corner
• Near Air Vents
• In Direct Sunlight
• With an Outside Wall Behind the Thermostat
• Near any Heat or Steam Generating Fixtures
• Near any Concealed Pipes or Chimneys

Installation at these locations will affect thermostat operation.

WALLPLATE INSTALLATION

Caution:
Electrical Hazard
Disconnect power before installing this product. Failure to do so can cause electric shock or equipment damage.

Mercury Notice:
This product is mercury-free. However, if this product is replacing a control that contains mercury, it needs to be disposed of properly. Contact your local waste management authority for instructions regarding recycling and proper disposal of the control.

WIRING

1. Turn Off Power to the Heating/Cooling System
2. Remove Old Thermostat
   Remove the old thermostat but leave the wallplate with wires attached. Do not remove the wallplate
3. Label Wires with Tags Label the wires using the supplied wire labels as you disconnect them.
4. Separate Wallplate from New Thermostat
   Remove the wallplate from the new thermostat and mount it onto the wall.
5. Mount Wallplate for New Thermostat Mount the new wallplate using the included screws and anchors.
   • Drill 3/16-in. holes for drywall
   • Drill 3/16-in. holes for plaster
6. Connect Wires Simply match wire labels.
   If labels do not match the letters on the thermostat, check “Alternate Wiring (Conventional Systems) on page 9 and connect to the terminal as shown (see notes, below).

Alternate Wiring (Conventional Systems)
If labels do not match the letters on the thermostat, check the chart below and connect to the terminal as shown here (See notes, below).

1. If there is a C or X wire available then you can connect with C terminal. If there is no C or X wire then no need to connect with C terminal.
2. If you have a heat pump without auxiliary/backup heat connect either the O or B, not both. If you do not have a heat pump, do not connect O or B. Wrap bare end of wire with electrical tape.
3. Place a jumper (a piece of wire) between Y and W if you are using a heat pump without auxiliary/backup heat.

Installation Tip
Do not overtighten terminal block screws, as this can damage the terminal block. A damaged terminal block can keep the thermostat from fitting on the sub-base correctly or cause system operation issues. Max Torque = 6in/Ibs.

1. Power supply.
2. Use either O or B terminals for reversing the valve.
3. Optional 24 VAC common connection when the thermostat is used in battery power mode.
4. Jumper (not supplied).
