Boiler settings ver. 1
There are separate setpoints for the upper and lower section of the storage tank.
The first column in the view shows the setpoint values. The second column shows
temperature values that have been adjusted by a function in the system, such as the
Home and Away
function.
Edit the setpoint values by tapping on the value. The difference between the minimum
and maximum value can be 2–10 °C.
Lower tank Upper tank Temperature limits, °C
Minimum Maximum Minimum Maximum
Factory settings 40 45 50 55
Supplementary heating enabled 60* 60*
Supplementary heating disabled 60* 85*
*Absolute maximum values.
Note that if the temperatures specified in heating circuits’ heating curves are
higher than those specified for the storage tank, the storage tank setpoints will be
automatically increased.
Operation without a desuperheater
In E series heat pumps without a desuperheater (‘P’ models) or when the
desuperheater is not used, both sensors will be installed in the top section of the
storage tank. Use the same settings for both sensors.
Optimizing heat pump operation
To achieve the best possible coefficient of performance across the year, keep
the storage tank temperature as low as possible. As a general rule, the lower the
temperature, the better the seasonal coefficient of performance.
Backup heating
The storage tank is primarily heated with the heat pump’s compressor. If the required
temperature is not reached within a specified period (1–24 h, see section
Other
settings
), the compressor will be switched off for safety reasons. The heat pump’s
electric immersion heater is used to heat up the storage tank instead. The following
alarm will be displayed:
Storage tank temperature not achieved in set time.
By default, the immersion heater will be used for 12 hours.
