Towerstat RF/BM
The Towerstat RF/BM consists of a free-standing battery-powered (2 x AA alkaline)
radio-frequency transmitter (TX), and a ‘boiler module’, which is a boiler-mounted
modular receiver (RX). The boiler module RX is mains powered by connecting to
existing wiring within the boiler, and controls a volt-free changeover switch according
to signals from the TX. The TX and RX must be linked by the RF setup process (see
below). The transmitter can then be positioned freely around the property, and will
control the boiler to bring the heating on and off according to automatic or manual
settings on the transmitter.
The transmitter can be programmed with two temperature levels: daytime (comfort)
and night set-back (economy). The transmitter can also hold a time programme to
provide automatic control of those daytime comfort and night-set back economy
temperatures. This will allow you to pre-set a programme as illustrated below. The
transmitter programme positions P1 – P6 are factory pre-set sequences which
cannot be altered. P7, P8 & P9 are user-adjustable programmes so that you can
enter a time programme of your choosing, with settings at one-hour intervals.

The boiler module RX must be installed by a qualified person. We recommend
that you obtain the services of a CORGI registered heating installer for any
work within your boiler.

Boiler module RX installation
N.B. some boiler control panels have a hinged steel cover. These are likely to
be unsuitable for the boiler-mounted modular receiver, as the steel cover will
effectively block the radio frequency transmissions between the transmitter
and receiver. In general you should avoid positioning metallic objects –
including mirrors - in the line-of-sight between transmitter and receiver.
Switch off the mains power to the boiler, and obtain access to the boiler control panel
following the manufacturer’s instructions. Boilers which are suitable for the
Towerstat RF/BM boiler module RX will already have a mechanical or digital timer
fitted, or may have a blanking-plate to cover the aperture where the timer can be
fitted. The boiler module RX can be fixed in place as a direct replacement for the
timer, and should be connected in the same way as the original timing device.
Boilers should have four electrical connections only, to the terminals marked 1 to 4.
In these cases the boiler module RX can be connected in the same way.
