The maximum temperature that can be set depends on the
boiler settings.
When setting a clock program, start this an hour before you
require the first hot water. This gives the boiler sufficient
time to heat up.

Central heating settings

You can set a number of specific central heating settings via: Menu
> Settings > System > CH system:
4 Pump control: When this option is switched on, the pump
switches off when there is no demand for hot water. This means
the pump runs for less time (saving electricity). As the pump is off
if the boiler is not on, it may take a few minutes for a radiator to
actually fill with hot water when you turn it on.
4 Heating rate: This allows you to determine how quickly or slowly
the controller responds. This parameter affects the pre-heating
and the control response.
Set this to Slowest for underfloor heating.
For the eVita, we recommend the setting Extra Slow.
4 Cooling rate: This allows you to indicate how quickly the home
cools or how well your home is insulated. The better the insulation,
the slower the home cools down. This parameter affects the
control strategies RTC and OTC+comfort. And the off-periods
between the burner coming on.
Cooling rate > Slowest: Gives long off-periods between the burner
coming on.
Cooling rate > Fastest: Gives short off-periods between the burner
coming on.
4 Max. pre-heat: The maximum time before a switch point that pre-
heating can begin (Time in minutes).
4 Min. CH temp.: Minimum desired temperature of the central
heating water. This setting is particularly useful for convectors.
4 Max. CH temp.: Maximum temperature of the control for the
central heating water. This is not the maximum temperature of the
boiler.
CAUTION
If this concerns a safety function, this must be set on the
boiler.
The engineer installing the controller can set a number of
specific settings.
