INSTALLATION INSTRUCTIONS—HWSTAT OPTIMUM VIBE PROGRAMMABLE THERMOSTAT
The OPTIMUM VIBE - Model HWSTAT is a baery powered hard-wired programmable thermostat. It MUST be installed
by a qualied person, in accordance with best pracse and current IEE wiring regulaons.
Before programming, complete all set-up instrucons.
The control set - when congured for T.P.I. control - meets the UK Government BEIS Department’s criteria for Class
IV control, contribung 2% towards energy eciency of the system.
The transmier is baery-powered (2 x AAA alkaline)
Installaon procedure: thermostat locaon / posioning
The thermostat should be located within the property bearing in mind the following requirements:
The thermostat has an on-board temperature sensor, which it uses to detect ambient temperature, and calculates
whether to send a demand or no-demand signal to the heang appliance. The thermostat should be located in a
main living area, where it is visible, there is unrestricted air-ow but it is not unduly inuenced by draughts or ex-
traneous heat sources: radiator / direct sunlight / lamp— please refer to the diagrams below:
Thermostat / backplate - installaon
Remove the thermostat from the backplate by inserng a at-bladed screwdriver into the recesses on the le– and
right-hand sides and gently lever to release the backplate.
Fit the backplate to the wall surface and connect wiring to the terminal block. See the wiring diagram on page 2.
The thermostat controls a volt-free changeover switch. Standard heang appliance connecons will be live feed /
live return (mains or low voltage) to the two terminals marked COM and NO.
Thermostat - installaon
Having completed the backplate wall-xing and wiring, place 2 x AAA alkaline baeries in the baery compartment
at the back of the transmier; ensure correct polarity. Now clip the thermostat onto the backplate: align the upper
two holes on the back of the thermostat with the pillars on the backplate, and pivot downwards, applying light
pressure unl the housing clicks into place. Switch on the power. If you remove the thermostat from the back-
plate you must switch o the power supply rst.
Set the me and day: Aer inserng baeries, the transmier will jump to me-seng mode, or during normal
operaon, touch SET for ve seconds, change the minutes with the up or down arrow, touch SET, change the
hours, touch SET, change the day, touch SET. Then touch the ON/OFF icon to put in run mode. Full set-up can be
completed later.
Note that - if you hold the thermostat for longer than a few seconds, it will start to detect your body temperature,
rather than the ambient room temperature. This will aect the calculaon of demand / no demand for heat. Re-
place the transmier onto the back-plate so that it will again start to detect the ambient room temperature.
Thermostat / backplate - installaon (cont’d)
The thermostat is intended for wall-mounng in a clean,
dry environment. It is a class II control, with an ambient
temperature rang from 0 to 500C. It has 60mm wall-xing
centres compable with standard paress boxes. A back-
plate channel is provided for surface-run wiring.
The thermostat controls a volt-free changeover switch and
will control the heang appliance via a two-wire connec-
on. The terminals are marked N O (normally open), N C
(normally closed), and COM (common). Normal heang
appliance connecons will be live feed & return (mains or
low voltage) to the two terminals marked COM and N O.
Wiring for volt-free switching:
Connect the volt-free boiler connecons
(Switch wire 1 / Switch wire 2) to COM & NO
(common and normally open)
Do not connect anything to terminal N C
Wiring for mains switching:
Connect 230V AC Live feed to COM
Connect the 230V AC switched live to N O
Do not connect anything to terminal N C
The VIBE HWSTAT thermostat is a baery powered double-insulated Class II control. Do not connect any neutral or
earth wire. Use a separate insulated single screw terminal block to provide earth connuity if required. Use an
otherwise empty insulated single screw terminal block to ‘park’ a neutral wire if required.
Complete the seng up procedure.
touch the UP arrow to raise the SET temperature above the measured ROOM temperature. Within 2 or 3 seconds
the demand symbol (see le) should appear in the display. There is an audible click as the switching relay oper-
ates. The heang appliance should now be running.
Before connecng the thermostat to the boiler, make sure that you have followed the boiler external thermo-
stat connecon instrucons. A mains connecon to a volt-free terminal could damage the boiler circuitry.

To open the conguraon menu, rst touch the transmier ON/OFF buon to turn the display o (touch
any buon to ‘wake-up’ the transmier, then touch the ON/OFF buon to turn o), then touch the SET and
UP buons at the same me for 5 seconds:
You will be viewing the rst of 15 opons which can be congured to adjust the operaon of the OPTIMUM
VIBE, to best suit the installaon and the user’s requirements.
Touch the UP or DOWN arrows to adjust the parameter, and touch SET to move sequenally through the
opons. Changes will be saved by pressing the ON/OFF buon. If no buon is touched for 10 seconds, the
display will ‘me-out’, but your changes will sll be saved.

53 Set if you chose OPs (Opmum Start) regulaon. For the best results, the me interval se-
lected should approximate the me taken to increase the room temperature by 1 degree.
54 Set if you chose TPi regulaon. Select a lower number for heang systems with a slow re-
sponse, and a higher number for heang systems with a fast response.
