The Horstmann ThermoPlus AS2-RF is a wireless room thermostat that has been designed
to make its operation very simple for the householder.
The built in automatic clock means it will not need setting or adjusting for BST and GMT
time changes.
The ThermoPlus will provide a Warm temperature setting at times pre-set by you installer
and day-to-day user adjustments are carried out using just three buttons.

The AS2-RF kit is supplied in two parts. The receiver which is hard wired to the combi or
conventional system boiler and the AS2-RF thermostat which can be used in any normal
domestic environment within a typical 30 metre range without the need for any costly or
disruptive wiring.

The AS2-RF thermostat kit is made up of two parts:
1 x receiver Receiver
1 x AS2-RF Transmitter
Both parts have been designed to be easily installed and offer maximum flexibility. No hard
wiring is required between the transmitter and the receiver. The receiver unit is hard wired to
the boiler and should be sited close to the existing wiring. The AS2-RF can then be positioned
up to 30 metres away -

Range will vary depending upon the composition, density and number

of walls between the AS2-RF transmitter and the receiver.

The ThermoPlus AS2-RF is battery powered and is intended for applications where running
cables to a boiler would be difficult. To conserve battery life there is an 8 second auto power
down mode on the indicator lights and the display back light. The LED target temperature
display will remain on, but not back-lit, at all times. The LED indicators will illuminate whenever
the +/- or ‘Warm/Cool’ buttons are pressed. The Back-lit display will operate whenever any of
the buttons located under the flap are pressed.

The Blue button situated under the flap will initiate the
frost protection mode when pressed, the word
’STANDBY’ will appear on the display, the thermostat
has been pre-programmed with a frost protection
temperature level of 7

the up and down arrow buttons.

PRESS FOR STANDBY / FROST PROTECTION

To remove the backplate from the receiver
undo the two retaining screws located on the
underside, the backplate should now be easily
removed. Once the backplate has been
removed from the packaging please ensure the
receiver is re-sealed to prevent damage from
dust, debris etc.
The backplate should be fitted with the wiring
terminals located at the top and in a position
which allows a total clearance of at least 50mm
around the receiver.

DDIIRREECCTT WWAALLLL MMOOUUNNTTIINNGG

The receiver should be ideally located near an
existing power supply within an easy wiring
location to the boiler. Offer the plate to the wall
in the position where the receiver is to be
mounted, remembering that the backplate fits
to the left hand end of the receiver. Mark the
fixing positions through the slots in the
backplate, drill and plug the wall, then secure
the plate in position. The slots in the backplate
will compensate for any misalignment of the
fixings.

The receiver backplate may be fitted directly on
to a single gang steel flush wiring box
complying with BS4662, using two M3.5
screws. The receiver receiver is suitable for
mounting on a flat surface only, it must not be
positioned on an unearthed metal surface.

During normal operation the receiver will indicate the AS2-RF demand status through the colour
of its LED, please refer to the RECEIVER STATUS INDICATOR LED section of this guide.

The AS2-RF also uses a combination of LED and LCD displays to assist the user to gain maximum
benefit from the thermostat, during normal operating periods, where no user intervention has
occurred, the AS2-RF will power down to maximise battery life, to ‘wake up’ the AS2-RF press
the ‘Warm/Cool’ for 5 seconds, the displays, both LED and LCD, will now illuminate and will stay
lit for a period of 8 seconds after the last button press.

the user guide.

Electronic equipment can in some circumstances be affected by electrical interference. If the
display becomes frozen or scrambled; or if you wish to revert back to the default settings

All necessary electrical connections should now be made. Flush wiring can enter from the rear
through the aperture in the backplate. Surface wiring can only enter from beneath the receiver
and must be securely clamped.
The mains supply terminals are intended to be connected to the supply by means of fixed
wiring.
The receiver is mains powered and requires a 3 Amp fused spur. The recommended cable sizes
are 1.0mm

2

or 1.5mm2.
The receiver is double insulated and does not require an earth connection, an earth connection
block is provided on the backplate for terminating any cable earth conductors. Earth continuity
must be maintained and all bare earth conductors must be sleeved. Ensure that no conductors
are left protruding outside the central space enclosed by the backplate.

the Installer. It is vital that care is taken to ensure a profile is selected that suits the lifestyle of
the householder concerned. The flow chart on page 8 of the user guide is designed to easily
guide you through the process of setting the required profile.

Profiles one to five are detailed on page 9 and 10 of the user guide.
