INSTALLATION INSTRUCTIONS
Application
This pack provides a wireless control solution for adding 2 wireless room
thermostats to heating systems, in order to split the heating system
into 2 separate zones and ensure compliance with the latest Building
Regulations.
Pack Contents & Product Descriptions
1 x ST9520C1005
Wireless enabled 7 day programmer with 2
output control relays for switching boilers, pumps
and zone valves in heating systems. It requires
permanent mains 230Vac power.
2 x DTS92E1020
Wireless digital room thermostat with energy
saving ECO function. It operates on 2 x AA alkaline
batteries, giving a battery life of at least 2 years
under typical operating conditions.
2 x table stand for DT92E (optional)
Other Honeywell products, not supplied in this pack, may be required
for a complete installation, depending on the application. For example
BDR91T1004 relay box. See Schematic System Layouts (below) or refer

System Operation
DT92E and ST9520C use 2-way communication on an 868MHz radio
frequency (RF) band to control the heating system.
ST9520C operates as the control hub of the system and the DT92E
thermostats are free to be positioned in suitable locations in the 2
separate heating zones.
This functionality is ideal for upgrading existing systems without a room
thermostat to ensure compliance with Building Regulations. It is also ideal
for refurbished systems, where running mains cable from the programmer
to the thermostats and back to the boiler is difficult or impractical.
There are various options for how to connect to the boiler. The simplest
is a direct 230Vac connection. If the boiler supports OpenTherm
communications technology, it is possible to control it using a 2-wire
connection from the ST9520C OpenTherm terminals. If the boiler is
located remotely, it is possible to send the switching signal from the
ST9520C to a remote located BDR91T relay box.

INSTALLING THE BDR91T WIRELESS RELAY BOX (IF REQUIRED) If the heating boiler is located remotely it is possible to control it using a wireless relay box BDR91T1000. This is not supplied in this pack and must be purchased separately. After installation it must be bound (paired) to the ST9520C timer and then the signal strength should be verified to ensure the location chosen is suitable. -
