2. Thermostat 2.1 Installing the thermostat
2.3 Normal status
Connect the thermostat to the control unit using the black cable. The first available channel (actuator connection) will flash.
Numbers 1 - 12 at the top of the display will show the channels that have been assigned. Time and day of week are also visible.
Use the horizontal keys to highlight the preferred channel. Press OK to confirm. Repeat for each thermostat.
When a thermostat sends a signal to the programming unit, the associated channel on the display will “flash” twice.
2.4 Operation Check If one thermostat is to control several channels, repeat the programming of the thermostat by disconnecting the black cable and reconnecting again.
To check whether the thermostat is signalling back to the control unit. First find the number on the back of the thermostat you wish to check. Next press the thermostat button on the display screen once. You will have two lines of information- actual temperature and specified temperature. Using the horizontal keys to view each thermostat, turn up or down the thermostat and wait for the specified temperature display to change. If the display changes then the system is functioning. If not the battery may require changing or the unit re-setting. See 2.2 then 2.1.
2.4a Temperature status and signal strength When the “thermometer button” is pushed, the current temperature settings and strength of the signal from the thermostat are displayed.
2.2 Erase channel assignment To erase the channel to which a thermostat is assigned, press SHIFT and . Select the channel to be erased using and . Press OK to confirm for 3 sec.
Use the horizontal keys to view each thermostat setting: 0 = no signal 1 = poor reception 2 = acceptable signal 3 = good signal 4 = excellent reception Press the “thermometer button” again to change min./max. setting. Note: If min. setting = max. setting, the temperature setting is blocked and will not be changed by turning the thermostat bulb. Confirm new setting by pressing OK.
2.5 Positioning thermostat The room thermostat should not be mounted on an external wall or near to a heat source such as TV, stereo, boiler or open fire. It should not be located so that it is exposed to direct sunlight. In very damp and steamy rooms, the thermostat should be located as far away as possible from the source of moisture. Thermostats must not be located where they can be directly splashed with water. Thermostats are normally positioned at 1.8 m from the ground level. 2.6 Operation Each room thermostat is installed and programmed with it’s own identification number. This ID-number is transmitted every time temperature information is sent S:\velta\Cotracts\Forms\velta genius programming
page 2/6
to the base unit. The ID number enables the base unit to distinguish between the various room thermostats and prevents confusion with other neighbouring systems. Each room thermostat sends control signals with temperature information between 2-30 minutes. The room thermostat transmits data as soon as the room temperature changes by 0.25°C or as soon as the set temperature is changed. When the room temperature setting is maintained, the transmitting interval is 30 minutes.
3 Setback 3.1 Set-back groups
3.3 Programming set-back temperature
Press MOON to view the set-back groups B and C.
After the set-back periods have been confirmed, “setback value” will be requested.
Each group has two set-back periods. Each set-back period can be assigned to channels and days independently of one another. Use and to select set-back group and confirm with OK. Factory setting: Group A is assigned to all channels on all days and the set-back period is from 10.00 pm to 5.00 am.
Use the and to change the set-back temperature between 1ºC and 9ºC. Confirm with OK.
3.4 Global Temperature set-back When the system is in normal status, it is possible to activate global temperature set-back. All temperature settings, independently of the other programmed values, are set-back by 4ºC until the global set-back is cancelled. Press SHIFT and CLOCK to activate global set-back. Global set-back is shown in the display. Cancel by pressing SHIFT and then CLOCK.
3.5 Holiday set-back This function is used to temporarily reduce all the temperature settings for a pre-set period between 1 and 90 days.
3.2 Programming set-back period
Press SHIFT and MOON. Use the and to select the number of days. Confirm with OK.
Program the selected Set-back group as follows: Use and to move the cursor between various positions Use = ON - = OFF to switch channels and days on and off Once a channel or day has been selected, it will remain visible.
The set-back period applies from 00.00 the following day. Program the set-back temperature using the and to change the set-back temperature between 1ºC and 9ºC. Press OK to confirm. To end the holiday set-back whilst it is still active: Press SHIFT and MOON. Use the and to select YES or NO to end the holiday set-back period. Press OK to confirm.
Press CLOCK and or to change the start/stop time for the channel/day. If the time-interval goes over midnight, e.g. from 10.00 pm. to 05.00 am, the day chosen refers to the set-back starting time. Confirm with OK. S:\velta\Cotracts\Forms\velta genius programming

If one channel is assigned to more than one set-back group that are active simultaneously, the set-back group with the longest reduction period will actually be assigned.

4 Alarm 4.1 General If the control unit does not receive signals from any thermo transmitter for at least 90 minutes, an alarm is given. The reason may be a flat battery in the thermo transmitter or the transmitter may be placed outside the system range. In the case of alarm, an alarm icon and the icon with the number of the affected channel will flash in the display. In addition an audio signal is given (if this option is selected, see 4.2). To acknowledge the alarm, press the SHIFT key. The buzzer is now quiet and the alarm icon is visible. The channel icon continues to flash. If a signal is received again, the display automatically returns in normal mode. As long as the Control unit does not receive a signal for the affected channel, the respective output is switched off and the valve will remain closed.
4.4 Battery Each thermostat is supplied with a 3.6 V 1900 mA Lithium battery. Batteries will last approximately 5 years in the display thermostat and approximately 10 years in the switch thermostat. It is advisable to change all batteries after 5 or 10 years to avoid unnecessary problems. The battery can be changed by house-owner. Make certain that the new battery is correctly connected. If not the thermostat may be seriously damaged. Never attempt to recharge the battery. After replacing any battery, the thermostat must be run in the Test Mode (see 4.5 and 2.3), then check the thermostat signal strength on the keypad display (see 2.4) to ensure that it functions correctly.
4.2 Audible alarm Press SHIFT and ďƒ§ and to select audible/inaudible alarm. Press OK to confirm.
4.5 Test mode The room thermostat is in a low energy status and does not send or receive any information until the moment it is first installed. This conserves energy and preserves the life of the battery. When first installed, the thermostat automatically enters the Test Mode enabling transmissions to be immediately checked. (N.B. After changing the battery, the thermostat has to be set in Test Mode manually.)
4.3 Autotest In this mode, all functions are tested in sequence. This takes about 15 minutes. Press SHIFT and then OK. All icons in the display are shown. Pump and channel 1 - 6 receive power and actuators 1 - 6 are opened. The actuators 8 -12 are then powered and opened in turn.
In Test Mode, signals are sent every 4 seconds for a period of up to 7 minutes before the thermostat reverts back to normal transmission periods. A red LED behind the battery cover also lights, showing when transmissions are made in test mode. To set the switch thermostat in test mode: turn the grey bulb to the highest setting and immediately select a different position on the red switch on the side of the thermostat.
N.B. Reset the grey bulb to the correct temperature setting once testing has been completed and reset the red switch. S:\velta\Cotracts\Forms\velta genius programming
