Important notes

• Paper Whiteness & Brightness levels of 90 (+/-5) should try to be achieved where possible. If not possible then notify Resideo of the closest alternative.
• Printing and finishing should be to the best quality achievable by the process and free of blemishes, smudges or other visible defects.

Installation

The THR842D wireless room thermostat comprises a THR842D Room Thermostat and a Relay Box. These devices communicate on an 868MHz Radio Frequency (RF) band to control a single heating system component such as a boiler, pump or zone valve. RF communication is 2-way, allowing high performance energy efficient control, display of boiler information, and easy setup and communications check features.

Relay Box

Installation Notes

• The RF link between the Room Thermostat (THR842D) and the Relay Box in Honeywell system packs is pre-configured at the factory and therefore should be installed at the same site.
• If products from individual system packs are separated, or mixed with other pre-configured system packs during installation, or a faulty unit is being replaced, the desired units must be specially configured to allow them to communicate with each other.
• This process is called Binding. Please refer to section 6) Binding / Rebinding Procedure.
• THR842D or Relay box will not communicate with other RF products that use different frequencies or communications protocols.
• The THR842D room thermostat requires no power source other than the batteries provided.
• The Relay Box requires a permanent 230V~ supply.
• The Relay Box should be installed before commencing the Room Thermostat installation.

Installing the Relay Box

• For best performance, install in an open space. Leave at least 30cm distance from any metal objects including wall boxes and boiler housing.
• Do not mount on metal wall boxes.
• EMC compliance considerations
• Keep AC mains supply/load cables separate from signal wiring.
• Refer to Code of Practice standards EN61000-5-1 and -2 for guidance

Locating the Room Thermostat

• For best performance, install in an open space where THR842D can sense the room temperature, and where the signal strength is high.
• The Room Thermostat can be mounted on a wall or on the optional table stand.
• Leave at least 30cm distance from any metal objects and at least 1 metre from any other electrical equipment.
• Select the preferred location and test the Signal Strength before installation.
