Installation Instructions

The Daintree Networks Wireless Thermostat (WTS10) operates seamlessly within the ControlScope® wireless building control platform. The WTS10 is a low voltage wireless commercial programmable thermostat that can connect to any single or multi-stage conventional or heat pump HVAC system. As part of the ControlScope system and using industry standard ZigBee® wireless communications, the WTS10 can be managed and programmed from any location using the ControlScope Manager (CSM) web application, eliminating the need for on-site, manual thermostat adjustment.

Installation Process

If this is a new thermostat installation, locate the thermostat 4 to 5 feet above the floor in accordance with applicable building codes. Install in a location that provides good airflow characteristics and avoid areas behind doors, near corners, air vents, direct sunlight, or heat generating devices. Installation in these areas could impact thermostat performance. Wiring must conform to all building codes and ordinances as required by local and national code authorities having jurisdiction for this installation.

1. Always turn off power to the air conditioning and/or heating system prior to installing thermostat.

2. Determine the HVAC equipment type. Note to Installer: Circle the type of equipment and giive this information to the commissioning agent:

A. 1 Stage Heat / 1 Stage Cool Conventional System B. 2 Stage Heat / 2 Stage Cool Conventional System C. 3 Stage Heat / 2 Stage Cool Conventional System D. 1 Stage Heat / 1 Stage Cool Heat Pump System

(without Auxiliary Heating)

E. 2 Stage Heat / 1 Stage Cool Heat Pump System

(with Auxiliary Heating)

F. 2 Stage Heat / 2 Stage Cool Heat Pump System

(without Auxiliary Heating)

G. 3 Stage Heat / 2 Stage Cool Heat Pump System

(with Auxiliary Heating)

3. Refer to the Wiring: Thermostat Terminals section to determine the number of wires necessary to install this thermostat with your system.

• A common connection between the HVAC unit and

the thermostat “C” terminal is required.

• When replacing an existing thermostat, and before

disconnecting any wires, mark each wire connected to the existing thermostat with the terminal letter to which it is connected.

• Make sure the disconnected wires do not slip back

through the wall opening; anchor them outside the wall opening.

4. Ensure that power to the air conditioning and heating systems is turned off.

5. Mount the WTS10 thermostat.

A. Remove the thermostat front body from the base. B. Guide thermostat wires through the center opening

in the base. Anchor them so they do not slip back into the wall.

C. Hold the thermostat base against the wall in the

desired thermostat location.

D. Mark placement of mounting holes as appropriate. E. Remove thermostat base from the wall. Install wall

anchors as required at the mounting hole locations.

F. Re-insert the wires through the center opening on

the base. Anchor them so they do not slip back into the wall.

G. Fasten the base to the wall using the supplied #6

screws into the wall anchors.

DT103 (Rev. 12.8.17)

6. Refer to Wiring: Thermostat Terminals and wire the terminals on the thermostat base to the attached HVAC equipment.

Testing

WARNING! Read BEFORE Testing

• Do not short across terminals on the gas valve or

at the heating or cooling system control board to test the thermostat installation. This could damage the thermostat and void the warranty.

• Do not select COOL mode if the outside temperature

is below 50° F (10° C). This could damage the controlled cooling system and cause personal injury.

• Ensure the power supply is correct and the display is

reading current room temperature.

Joining the ZigBee Wireless Network

After successfully completing the Installation Test the WTS10 is ready to communicate with the Daintree Wireless Area Controller (WAC) and be commissioned and configured using the ControlScope Manager (CSM) webbased application. The thermostat automatically tries to join the WAC network every 5 minutes. The WAC must be commissioned and Add New Devices must be initiated on the WAC before the thermostat can join the ZigBee wireless network.

For information about configuring the thermostat using CSM, see the on-line help.

Once the thermostat is joined, it ignores its built in schedules. The WAC passes configuration information like

setpoint, heat/cooling mode, lock levels etc. at the start of each CSM schedule.

If the thermostat loses communication with the WAC the following things will happen: (1) Thermostat continues to use the existing configuration set by the WAC. (2) Keypad automatically unlocks after 30 minutes to allow manual changes. (3) If remote temperature sensor(s) are enabled, and the thermostat does not receive a remote temperature report within 15 minutes, it will switch to its built-in temperature sensor.
