Honeywell DT92E Wireless Room Thermostat
Installation
The DT92 wireless room thermostat comprises a DT92 Room Thermostat and a BDR91 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.
Installation Notes
- The RF link between the Room Thermostat (DT92) and the Relay Box (BDR91) 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.
- DT92 or BDR91 will not communicate with other RF products that use different frequencies or communications protocols.
- The DT92 room thermostat requires no power source other than the batteries provided.
- The BDR91 Relay Box requires a permanent 230V~ supply.
- The Relay Box should be installed before commencing the Room Thermostat installation
Installing the BDR91 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 DT92 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

Binding
The binding operation shown is required if:
- any of the system components (Room Thermostat or Relay Box) are replaced
- Relay Box has incorrect or no binding data stored (for example, when pre-bound system pack components have been mismatched).
Reset stored data in Relay Box
Put Relay Box into Binding Mode
Reset stored data in Room Thermostat
Put Room Thermostat into Binding Mode
Bind Room Thermostat to Relay Box
Now go to Section 3.2 RF Communication Test
