QUICK START

Thank you for purchasing a Robertshaw®thermostat. This manual will describe how to install and test the Robertshaw single stage thermostats RS4110, RS5110, RS6110, two stage RS4220, RS5220, RS6220, and three stage* RS4320, RS6320 thermostats. For complete operation instructions, refer to the Robertshaw User Manual.

Use the model number to identify your thermostat.

These thermostats have three main parts:

A. The backplate – mounts to the wall and has wire connections. B. The body – snaps to the backplate and contains the electronics and

programming buttons.

C. The cover – snaps to the top of the body and swings up to give

access to the programming buttons.

Recycling Thermostat

If this thermostat is replacing a thermostat that contains mercury in a sealed tube, do not place your old thermostat in the garbage. Contact your local waste management authority for instructions regarding proper disposal of the thermostat. If you have any questions, call Robertshaw technical support at 1-800-445-8299.

* Three stages of heating available for heat pump applications only.

IMPORTANT SAFETY INFORMATION WARNING:

• Always turn off power at main fuse or circuit breaker panel before installing, removing, cleaning, or servicing thermostat.

• Read all 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.

• This is a dual powered thermostat that will operate on 24V AC or batteries.

• 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.

• Do not connect ground to any terminal in this unit.

• This thermostat is configured with automatic compressor protection to prevent damage because of short cycling or extended power outages. Short cycle protection provides a delay between compressor cycles on heat pumps.

Replacing Existing Thermostat

1. Turn off power to heating and cooling system.

2. Remove cover from old thermostat to expose wires.

3. Disconnect wires one at a time from existing terminals. Use enclosed labels to mark existing wires. Refer to cross references in Table 1 if existing wiring does not directly match the labels.

4. Remove existing thermostat base from wall.

Installing the Robertshaw Thermostat Base

NOTE: For new installations, mount the thermostat on an inside wall, five

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 locations will affect thermostat operation.

1. Be certain power is off to the heating and cooling systems.

2. Remove the backplate by placing your finger through the wire opening. Pull the backplate straight out from the body.

3. Place the backplate in position on the wall. Pull the wires through the wire opening.

4. Hold the backplate level and mark the mounting holes on the wall.

5. Drill the marked holes using a 5 mm (3/16 in.) drill bit.

6. Tap in the wall anchors and secure the base to the wall with the supplied screws.

NOTE: The thermostats are designed to also mount on a single gang

junction box.

Providing Power to the Thermostat

To take advantage of the Pop-Up Wizard, power should be applied when the settings are ready to be entered. Fill in the chart in the Pop-Up Wizard section before applying power.

These thermostats will run on either two AA batteries or 24V AC. If the common wire from the transformer is not available, the unit must be powered by two AA batteries.

Thermostats with batteries and powered by 24V AC will continue to function if the 24V AC fails.

Maintaining the Batteries

When the batteries are low, the thermostat will enter a low power mode. Low battery mode has two levels.

• LEVEL 1: The low battery icon will be displayed.

• LEVEL 2: The low battery icon will flash indicating that THE SYSTEM WILL NOT OPERATE.

System Switch Selection

The body of the thermostat has two switches on the backside. They are accessible by removing the backplate from the body. The installer should set these to match the system.

If the thermostat is controlling a heat pump system, set the first switch to Heat Pump. Set the second switch based on the type of the backup heating system.

If the thermostat is controlling a non-heat pump system, set the first switch to Non-Heat Pump. The second switch must be set to match the system as Gas or Electric.

If Non-Heat Pump and Gas are selected, the heating system will control the fan. If Non-Heat Pump and Electric are selected, the thermostat will control the fan. If Heat Pump is selected, the thermostat will control the fan.

Connecting the Wires

1. The wire ends should be stripped back 8 mm (5/16 in.).

2. Use the Wiring Diagrams and secure the wires into the terminal strip. If replacing another thermostat, the wires should have been labeled. Match the labels to the terminals. Tighten the screws.

3. Pull lightly on each wire to ensure the connection is secure.

NOTE: Nightlight feature is only enabled when the RH/R and C terminals

are connected.

Applying Power

Before applying power, fill in the chart in the Pop-Up Wizard section of this manual.

When 24V AC power or battery power is first applied to the thermostat, the display will show the model number followed by the Pop-Up Wizard. The thermostat will start normal operation following the Pop-Up Wizard.

Power is applied to the thermostat two ways:

1. Installing the batteries.

2. Not installing the batteries and connecting the thermostat body to a backplate that has the C terminal connected and 24V AC present.

NOTE: A thermostat powered by 24V AC will use the batteries as backup

power if the 24V AC fails.

Installing Batteries

To remove the battery compartment gently squeeze the ribbed edges on both sides.

The battery compartment will pull down from the thermostat body and will detach. Install two AA batteries following the polarity as shown inside the compartment. Place compartment back into the thermostat.

Connecting The Body

Attach the thermostat body to the backplate by holding it directly in front of the backplate. The edges will match and the wiring connections will make contact. Push the body in until it snaps in place.

Pop-Up Wizard

The Wizard routine will display factory default settings. Each setting will display for ten seconds. Use the or buttons to change the setting. Settings that are not changed will operate with the values that are displayed. To fast forward through the Wizard, press Edit Schedule. The Wizard can be exited by pressing Start/Stop Schedule. This will save the settings and place the thermostat into operation.

Use this chart to write down the desired settings before applying power. Settings may vary by model.

After the Wizard has configured the thermostat, the settings can be edited by pressing and simultaneously. This will allow you to change settings.

Factory settings that have not been changed will use the default settings for operation.
