MANUAL BOOSTER: TIMER
This function enables the radiator to reach optimum temperature rapidly and
independently of the thermostat setting.
Hold down button ❸ for a few seconds. The red indicator ❹ will ash for 2
hours. The radiator automatically returns to heating mode at the end of the cycle.
You can stop the function by holding down button ❸; the indicator will stop
ashing.
PROGRAMMED BOOSTER: TIMERPROG
This enables the booster start time to be programmed so that it comes on at the
same time everyday. User-friendly programming: no time to set, no complicated menu!
By pressing button ❸ for 5 seconds, you can record the time the booster was
activated (i.e. when the button was pressed). The indicator ashes in three series of
three to indicate that the TIMERPROG is activated. After this series of ashes, the
indicator ashes normally to indicate that the TIMER is on.
The booster will now start every day 30 minutes before the recorded time.
Example:
- Day 1: 7 AM.
Press down for 5 seconds, the indicator ashes (in three series of three), the
time is recorded. The Booster is on.
- Day 2: 6:30 AM, the Booster comes on for a 2-hour period.
The programmed setting can be cancelled by turning the appliance off (button ❶).
The manual TIMER can be activated without affecting the TIMERPROG.
As with manual operation, the TIMERPROG can be stopped by pressing button
❸ without affecting the programmed setting.
4.5 Programming by pilot wire (option)
Your Acova appliance can be regulated by a 6-command programming unit
(COMFORT, COMFORT -1°C, COMFORT -2°C, ECO, FREEZE PROTECTION,
HEATING STOP).
NOTE:
You can use the "freeze protection" command on your Acova appliance’s electro-
nic thermostat for load-shedding (option available with some programming units).
When using the programming function, it is vital to use appliances of equivalent
technology to ensure optimum levels of comfort.
IMPORTANT Boost programming by pilot wire:
When the appliance is programmed by pilot wire, the booster function overrides
all the programmed commands except the programmed Heating stop command.
Press button ❸ for the booster function in pilot wire mode: ECO, COMFORT
-1°C, COMFORT -2°C, FREEZE PROTECTION: the red indicator ashes, the
appliance is in booster mode for 2 hours.
In the programmed Heating stop by pilot wire mode (load-shedding function): the
red indicator ❹ ashes but the appliance does not heat up as long as the Heating
stop command is maintained.
