following measures:  

The following cautions must be observed:  

CommandPlus Wiring  

Before connecting the wires to the back of the thermostat, detach  

the display front from the base.  

SunStat Sensor Installation  

• The SunStat sensor can be installed with or without electrical  

conduit depending on code requirements. Conduit is  

recommended for added protection against nails and screws.  

SunStat^® CommandPlus™  

ALWAYS install the floor sensor included with the thermostat.  

NEVER put the system into full operation until the tile or flooring installer  

verifies all cement materials are fully cured (typically two to four weeks  

after installation).  

• Reorient or relocate the receiving antenna.  

While holding the base section in one hand, with the other pull  

gently up holding the sides of the thermostat towards the bottom  

(near RESET button), pivoting away from the base.  

• Increase the separation between the equipment and receiver.  

• Consult the dealer or an experienced radio/TV technician for help.  

• Do not place the sensor in the same conduit as the power  

leads to avoid possible interference. Open a separate knock-  

out in the bottom of the thermostat box. Feed the sensor (and  

conduit, if used) through the knock-out, down through the  

cut-out in the bottom plate, and out into the floor where the  

heating cable will be installed.  

Installation and  

Operation Manual  

ALWAYS use insulated copper wires rated for 90°C (194°F) and 600 V  

minimum. Do not use aluminum.

Summary of Contents

• Page 1: television reception can be determined by turning the equipment off and on. The user is encouraged to try to correct the interference by various measures. Before connecting the wires to the back of the thermostat, detach the display front from the base. The SunStat sensor can be installed with or without electrical conduit depending on code requirements. Always install the floor sensor included with the thermostat. Never put the system into full operation until the tile or flooring installer verifies all cement materials are fully cured. Always use insulated copper wires rated for 90°C and 600 V minimum. Always wire all circuits as Class 1, electric light & power circuits. Do not place the sensor in the same conduit as the power leads to avoid possible interference. A qualified person should run a dedicated circuit from the main circuit breaker panel to the control location. Read this manual before using this equipment.
• Page 2: Floor sensor error indicates the floor sensor is disconnected or needs to be replaced. Make sure the mortar has had time to fully cure before operating the system for more than a brief test. Programming may be lost—verify all settings. The default schedule has a weekdays program and a weekends program. To create a new schedule, select Change Days. Smart Start will begin heating the floor early to meet the scheduled temperature on time. Press the TEST button on the GFCI monthly to verify that it is operational. If the GFCI trips during normal operation, press the RESET button to resume operation. It is strongly recommended that a qualified, licensed electrician install the heating cables and related electrical components. Warm Weather Shut Down saves energy by turning off the heating system when the outdoor temperature is above the setting.
