Leviton WS0TH-D00 Programmable Thermostat

WARNINGS AND CAUTIONS

• TO BE INSTALLED AND/OR USED IN ACCORDANCE WITH APPROPRIATE ELECTRICAL CODES AND REGULATIONS.
• IF YOU ARE NOT SURE ABOUT ANY PART OF THESE INSTRUCTIONS, CONSULT AN ELECTRICIAN.
• THERMOSTATS ARE INTENDED ONLY FOR USE INDOORS, IN DRY LOCATIONS, AND WITH PERMANENTLY INSTALLED FIXTURES.

DESCRIPTION

The 24VAC Thermostat provides digital temperature control of heating and cooling–with wireless communication to multiple Leviton devices. It is designed for use with most basic gas/electric furnace/air conditioning units, PTHP/PTAC Systems, 4-pipe, or 2-pipe fan coil systems. Solid-state control outputs allow switching of electronic and relay loads of 1.5 amps. This control operates from a single setpoint with automatic changeover between heating and cooling. The fan cycles on/off with calls for heating or cooling or can operate continuously in either low, medium, or high speed. The control can be placed in economy mode or off mode with 40° freeze protection. Economy mode is enabled and disabled by one or more compatible transmitters.

PROGRAMMING THE THERMOSTAT
Connect the thermostat to a 24VAC power source for initial setup. DO NOT CONNECT THE OTHER WIRES UNTIL THIS STEP IS COMPLETE. PREVENT ALL OTHER WIRES FROM TOUCHING DURING THIS PROCESS TO AVOID DAMAGE TO THE THERMOSTAT. DAMAGE DUE TO INCORRECT WIRING WILL VOID WARRANTY. The programming mode has a time limit of 10 minutes. After 10 minutes, the thermostat will resume normal operation. The default values mentioned throughout this section refer to factory programmed settings. If the thermostat has been custom programmed, the defaults may not apply.

NOTE: For programming large numbers of devices, an accessory is available to copy settings from one device to another. Contact Leviton for details.

INSTALLATION

Junction box mounting is highly recommended. For optimal radio performance do not mount or place the receivers close to the floor or inside a metal housing.

INSTALLATION OPTION A:

Heat Pump Configuration

• To avoid risk of fire, shock, or death, TURN OFF POWER at circuit breaker or fuse and verify that it is OFF before installation begins. Make sure that it remains OFF until installation is complete.
• Read all steps for this option before taking any action to install thermostat.
• If retrofitting old thermostat, remove old thermostat, carefully noting the wire connections on the old unit. Record wire color and terminal legends (Cable wire color for Control Feed,
  Load Feed, Common, Auxiliary Heat, Compressor, Low Fan, High Fan, and Reversing Valve). Refer to Table A.
• Install mounting bracket to the junction box with provided mounting screws.
• Wire thermostat according to function as shown in Figure A.
• Push wires into junction box. Rest bottom of thermostat on mounting tabs in mounting plate.
• Push top of thermostat towards wall and secure into place with self-tapping screw.
• Turn power on.

INSTALLATION OPTION B:
4-Pipe Fan Coil Configuration

• To avoid risk of fire, shock, or death, TURN OFF POWER at circuit breaker or fuse and verify that it is OFF before installation begins. Make sure that it remains OFF until installation is complete.
• Read all steps for this option before taking any action to install thermostat.
• If retrofitting old thermostat, remove old thermostat, carefully noting the wire connections on the old unit. Record wire color and terminal legends (Cable wire color for Control Feed, Load Feed, Common, Auxiliary Heat, Compressor, Low Fan, High Fan, and Reversing Valve). Refer to Table A.
• Install mounting bracket to the junction box with provided mounting screws.
• Wire thermostat according to function as shown in Figure B. NOTE: If the mechanical system has only two fan speeds: Green – Low Fan, Violet – High Fan, Orange – Not used.
• Push wires into junction box. Rest bottom of thermostat on mounting tabs in mounting plate. Push top of thermostat towards wall and secure into place with self-tapping screw (included).
• Turn power On.

INSTALLATION OPTION C:

2-Pipe Fan Coil Configuration

NOTE: Continuous fan is not available on 2-Pipe with Aquastat systems. A continuous fan is available on 2-Pipe with electric heat systems.

• Follow instructions for a 4-Pipe installation but use Figure C for 2-Pipe Fan Coil with Aquastat or Figure D for 2-Pipe Fan Coil with Electric Heat.
• Push wires into the junction box. Rest bottom of the thermostat on the mounting tabs in the mounting plate.
• Push top of the thermostat towards the wall and secure it into place with a self-tapping screw (included).
• Turn the power On.

PROGRAMMING THE RADIO RECEIVER

The thermostat can be configured to operate with many Leviton transmitters. Depending on the transmitter type and the intended application, the thermostat will need to be programmed to operate in Rocker Mode, Momentary Mode, Toggle Mode, or Scene Mode. Multiple modes can be used with one thermostat. For transmitter installation instructions, see appropriate installation guide. Select the desired Learn Mode below to program the thermostat.

CLEAR MODE:
Clearing the Switch Memory

• In order the clear the switch memory within the thermostat, use the following steps:
• Press and hold the UP and DOWN buttons until CLR appears on the display (approximately 10 seconds).
• This will delete all associated transmitters from the memory.

LEARN MODE 0:
Rocker Mode – Wireless Switch Control of Thermostat

Rocker Mode is usually used with Leviton Wireless Light Switches. The thermostat goes into occupied mode when the top of the rocker switch is pressed and unoccupied mode when the bottom of the rocker switch is pressed.

• Place the thermostat into Learn Mode by pressing and holding the UP and DOWN buttons until LRN appears on the display (approx. 5 seconds). The display will alternate between LRN and 0 indicating that it is in Learn Mode 0 – Rocker Mode.
• Press one of the rockers on the Leviton Wireless Light Switch. The display on the thermostat will briefly display ADD indicating that it has added that transmitter.
• The display will resume alternating between LRN and 0 – add more transmitters as desired for this mode (up to 30). The small digit on the display will indicate the number of receivers in memory for each mode.
• To delete a transmitter from the thermostat, press the wireless light switch again. The display on the thermostat will briefly display DEL indicating that it has deleted that transmitter.
• Exit Learn Mode by pressing and holding the UP and DOWN buttons until LOC appears on the display or wait 30 seconds to normal operating mode. This indicates that all learned transmitters have been locked into memory on the thermostat.

NOTE: These steps are also used for Manual On/Auto Off – when learning a wireless occupancy sensor.

LEARN MODE 1:

• Press and release the UP button. The display will alternate between LRN and 1, indicating that it is in Learn Mode 1 – Momentary Mode.
• Insert a key card into an Leviton Key Card Access Switch. The display on the thermostat will briefly display ADD indicating that it has added that transmitter.
• The display will resume alternating between LRN and 1 – add more transmitters as desired for this mode.
• To delete a transmitter from the thermostat, remove the key card (if inserted) of a learned switch and insert it again. The display on the thermostat will briefly display DEL indicating that it has deleted that transmitter from memory.
• Exit Learn Mode by pressing and holding the UP and DOWN buttons until LOC appears on the display or wait 30 seconds to normal operating mode. This indicates that all learned transmitters have been locked into memory on the thermostat.

NOTE: These steps are also used for Auto On/Auto Off – Occupancy Sensor Control.

LEARN MODE 2:
Toggle Mode – Toggle Mode is available for future product releases.

• Place the thermostat into Learn Mode by pressing and holding the UP and DOWN buttons until LRN appears on the display.
• The display will alternate between LRN and 0 indicating that it is in Learn Mode 0.
