Optimum Vibe User manual

INSTALLATION INSTRUCTIONS—HWSTAT OPTIMUM VIBE PROGRAMMABLE THERMOSTAT
The OPTIMUM VIBE - Model HWSTAT is a baery powered hard-wired programmable thermostat. It MUST be installed
by a qualied person, in accordance with best pracse and current IEE wiring regulaons.
Before programming, complete all set-up instrucons.
The control set - when congured for T.P.I. control - meets the UK Government BEIS Department’s criteria for Class
IV control, contribung 2% towards energy eciency of the system.
The transmier is baery-powered (2 x AAA alkaline)
Installaon procedure: thermostat locaon / posioning
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 heang 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 inuenced by draughts or ex-
traneous heat sources: radiator / direct sunlight / lamp— please refer to the diagrams below:

Thermostat / backplate - installaon
Remove the thermostat from the backplate by inserng 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 heang appliance connecons will be live feed /
live return (mains or low voltage) to the two terminals marked COM and NO.

Thermostat - installaon
Having completed the backplate wall-xing and wiring, place 2 x AAA alkaline baeries in the baery compartment
at the back of the transmier; 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 unl 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: Aer inserng baeries, the transmier will jump to me-seng mode, or during normal
operaon, 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 aect the calculaon of demand / no demand for heat. Re-
place the transmier onto the back-plate so that it will again start to detect the ambient room temperature.
Thermostat / backplate - installaon (cont’d)
The thermostat is intended for wall-mounng in a clean,
dry environment. It is a class II control, with an ambient
temperature rang from 0 to 500C. It has 60mm wall-xing
centres compable with standard paress boxes. A back-
plate channel is provided for surface-run wiring.
The thermostat controls a volt-free changeover switch and
will control the heang appliance via a two-wire connec-
on. The terminals are marked N O (normally open), N C
(normally closed), and COM (common). Normal heang
appliance connecons 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 connecons
(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 baery 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 connuity if required. Use an
otherwise empty insulated single screw terminal block to ‘park’ a neutral wire if required.
Complete the seng 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 heang appliance should now be running.
Before connecng the thermostat to the boiler, make sure that you have followed the boiler external thermo-
stat connecon instrucons. A mains connecon to a volt-free terminal could damage the boiler circuitry.

To open the conguraon menu, rst touch the transmier ON/OFF buon to turn the display o (touch
any buon to ‘wake-up’ the transmier, then touch the ON/OFF buon to turn o), then touch the SET and
UP buons at the same me for 5 seconds:
You will be viewing the rst of 15 opons which can be congured to adjust the operaon of the OPTIMUM
VIBE, to best suit the installaon and the user’s requirements.
Touch the UP or DOWN arrows to adjust the parameter, and touch SET to move sequenally through the
opons. Changes will be saved by pressing the ON/OFF buon. If no buon is touched for 10 seconds, the
display will ‘me-out’, but your changes will sll be saved.

05 If you set a frost-protecon temperature, the heang will be switched on when the
measured temperature falls below this level, even if the transmier has been turned o.
10 0 - (default) Room and Set temperatures displayed. 1 - only Set temperature displayed
51 76— you can set every day with a dierent programme
526—two programme sequences can be set, one for weekdays, one for weekends. The fac-
tory default programme shown in the user instrucon is the default programme for both.

53 Set if you chose OPs (Opmum Start) regulaon. 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 regulaon. Select a lower number for heang systems with a slow re-
sponse, and a higher number for heang systems with a fast response.
55 Set if you chose TPi regulaon. Sets the temperature below the set-point at which TPi con-
