IMPORTANT SAFETY INFORMATION

WARNING: ELECTRICAL SHOCK HAZARD – Turn off power at the main power source by unscrewing fuse or switching circuit breaker to the OFF position before installing, removing, or cleaning this thermostat.

WARNING: FIRE AND ELECTRIC SHOCK HAZARD – This device should be installed by a qualified service technician with due regard for safety as improper installation could result in a fire and electric shock hazard.

WARNING: FIRE AND ELECTRICAL SHOCK HAZARD – This is a 24V AC low-voltage thermostat. Do not install on voltages higher than 30V AC.

• Do not switch system to cool if the temperature is below 50°F (10°C). This can damage your cooling system and may cause personal injury.

• 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.

• All wiring must conform to local and national building and electrical codes and ordinances.

• Use this thermostat only as described in the manual.

Sensor WiringThe thermostat will accept two types of temperature sensors. The standard two wire sensor andthemoreadvancedfourwiresensorthatiscapableofperformingadditionalcontrolfunctions.

Two Wire SensorsThe standard two wire sensors are suitable for room temperature monitoring only. There are a number of types of two wire sensors available, an overview is provided below. Two wire sensors connect to the Room Sensor terminal and the Common terminal next to it on the thermostat. Two wire sensors are not polarity dependent.The SMART-R-02 – Uses two wires to communicate the room temperature to the thermostat. Multipleunitscanbeusedforaveraging.TheSMART-R-02sensorisfittedwithaswitchthatinitiatestheafterhoursruntimerthatisincorporatedintotheSMART4000controller. The SMART-R-02 sensor is supplied as standard in the box with each thermostat controller.

You must also set economy cycle parameters in theChangeEconomySettingsmenu(seepage24).Theeconomycyclereliesonoutsideairtemperature humidity values being available to the thermostat.

Economy Checklist1. Wire the fresh, return and relief/spill dampers to the thermostat analog outputs. Note

which thermostat output is controlling which damper. For example, analog output 1 (Y1) can be set to control the return air damper, while analog output 2 (Y2) may be set to control the fresh air and spill damper (as shown in the example above).

2. Wire the room temperature sensor to the thermostat. Two wire or four wire versions of the sensors are acceptable. Wire the four wire sensor to the S1, S2, S3, S4 terminals. Set all four DIP switches in the sensor to ON. This will define the sensor function as outside air sensing. See the manual supplied with the sensor for more details on switch settings and other functions of the sensor.
