SAFETY WARNING Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and air-conditioning equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment by an unqualified person could results in death of serious injury. When working on the equipment, observe all precautions in the literature and on the tags, stickers, and labels that are attached to the equipment.

Introduction The Trane touch screen wall sensor THP05 is easily installed and configured with multiple options. It is designed to communicate via Modbus with HVAC Airfinity rooftop unit equipped with controller module CH536. Keep this user guide in an accessible area for reference. Read this manual thoroughly before operating or servicing this unit.

Warnings, Cautions, and Notices Safety advisories appear throughout this manual as required. Your personal safety and the proper operation of this machine depend upon the strict observance of these precautions. WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. CAUTION Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. It could also be used to alert against unsafe practices. NOTICE Indicates a situation that could result in equipment or property-damage only accidents.

CAUTION Take Precautions During Installation! If replacing an existing sensor, label the wires before removal. Electronic controls are static-sensitive devices. Properly discharge yourself before manipulating and installing the sensor.

CAUTION Protecting the System! All sensors are designed for use as operating units only and are not safety devices. Tampering with the device or unintended application of the device will void the warranty.

Equipment/Software supported Thermostat operates with controller module CH536 of Airfinity rooftop unit. Multi-zone systems are not supported. Thermostat is not compatible with BMS (Building Management System) communication interface (ModBus, LonTalk or BACnet (MSTP)). The controller module CH536 must be using software version 2.06 or later.

Installation Location guidelines • Do not install on an outside wall. • Do not install in areas with direct heat source. • Do not install near any air discharge grill. • Do not install in areas exposed to direct sunlight. • Ensure the sensor has sufficient air circulation. • Ensure the mounting wall surface is flat and clean. Installing the thermostat

1. Remove the security screw from the bottom of the thermostat (if present). 2. Firmly grasp the sensor and pull up on the bottom to remove the front cover. 3. Feed the wires from the wall through the backside of sensor base. 4. Ensure the thermostat is oriented by the top indicated on the inside and then mark the top/bottom mounting-hole locations on the wall. 5. Install the provided wall anchors and then affix the thermostat base to the wall using the provided screws. 6. Strip the wire coating from the ends of each wire approximately 0.25 inch. 7. Insert the wires into the wire terminals (per terminal identification below) and tighten down the terminal screws to secure wire. 8. Push any excess wire length back into the wall and then replace the thermostat cover. Once the cover snaps on, the thermostat powers up. 9. Replace the security screw on the bottom of the sensor to avoid tampering.

Power and Communication Wiring Important: The current display is designed to control only 1 rooftop unit. It is imperative to respect wiring of the power supply and of the communication according to the scheme below to guarantee correct function of the thermostat.

Apply 120 Ω terminal resistance (not included in the packaging) between terminal + (13) & - (14), if end device of serial RS 485 Bus, when a communication cable is longer than 200 m.

Maximal length of the communication and power cables is 500 m. It is needed to set a communication type in Service display. There is “None” by default. Setting in Service display (Menu BAS -> Communications):

Type Modbus Speed 38400 Modbus parity N Modbus StopBits 1 Modbus Address 001

System mode is set as OFF after the first thermostat start. When power supply is lost during thermostat operation, then it is kept last system mode and last occupancy mode in thermostat memory. So when power supply is back then the unit will operate according to the last setting. It is recommended to check Clock & Date settings in case of power supply interruption within more than 24 hours. Other parameters are saved permanently in memory, except of display color.

Then the button System mode is active and it is possible to select a system mode (Auto, Cool, Heat, Off) along with required setpoint. Touch System mode button to select required mode, the system status of selected mode is visible in right upper corner. Need to wait 1 s (refreshing time) to have a feedback about actual mode. Override function is deactivated when Override time is elapsed or by a touch on the Override button. Override function has higher priority than a schedule so it can overlap a following schedule. Change the setpoints directly on the home screen if required.

Manual control Manual control is active when Schedule is Disable. Touch the System mode button on the home screen to select required system mode, the system status of selected mode is visible in right upper corner. Need to wait 1s (refreshing time) to have a feedback about actual mode. Change the setpoints directly on the home screen if required. Indoor fan mode Button Indoor fan mode is visible on the home screen when Schedule is Disable (manual control) instead of Override button.

There is a possibility to set the indoor fan to mode Auto (Cycling) or to ON (Continuous) by a touch of the button Indoor fan mode (the first touch: fan mode is ready to change, the second touch: “On”, the third touch: “Auto”) in manual control. The relevant selection will be temporarily displayed on the home screen instead of Indoor temperature. No confirmation is required. Need to wait 1-2 s when required selection is done, then it will switch again to indoor temperature displaying and indoor fan mode is set.

Indoor fan mode Auto (Cycling) means that the indoor fan stops when a setpoint is reached, in another case the fan runs. Mode On (Continuous) means that the fan run all the time even the setpoint is reached, except unoccupied mode and setpoint reaching, then the fan stops.
