9.2 Room temp.
This is used to set the desired room temperature. The
plus and minus buttons are used to set the desired
temperature, displaying the so-called “setpoint”
temperature in brackets. The actual value is shown in
front of the brackets.
If heating circuit 3 or cooling is installed, the symbol for
room temperature is displayed with the text “3” at the
bottom right of the menu.
If you want to schedule a temperature reduction, you can
continue to the Night reduction or Holiday submenus.
You can select
Room sensor No in the Installer/Define
system/Heating system
menu. This can be done for
each heating system if it is difficult to find a position for
the room sensor, if the floor heating system has separate
room sensors, or if you use a fireplace or open stove. The
alarm LED on the room sensor still functions as normal.
If you use the fire or open stove only occasionally, the
firing process can affect the room sensor and reduce
the temperature supplied to the radiators. It can then
get cold in other parts of the house. The room sensor
can temporarily be deselected during the firing process.
The EcoZenith then provides heating to the radiators
using the set heating curve. The radiator thermostats
reduce the heating supplied to the section of the house
where a fire is burning.
9.2.1 Setting without a room sensor
If a room sensor has not been installed (this can be
selected from the Installer/Define system/Heating circuit
menu), the room temperature is adjusted by changing
the house’s temperature needs to match differing
outdoor temperatures.
Proceed as follows:
• Increase or decrease heating circuit 1 by a few steps
• Wait 24 hours before making the next adjustment
(if the indoor temperature is still not correct).
• NOTE: The value displayed is the ratio between
curve inclination and curve adjustment and has a
breakpoint at an outdoor temperature of 0ºC.
!
The thermostats of the radiators
must be fully open and well operat-
ing when the system is tuned.
The above menu shows heating circuit 1 without a room sensor
(top line) and heating circuit 2 with a room sensor (bottom line).
On adjustment of heating circuit 1 (top line), the water
temperature to the radiators is changed in relation to the
outdoor temperature. The changes automatically take the
heating circuit characteristics into account.

9.2.2 Outdoor Sensor/Room
Sensor Faults
If a fault occurs with an outdoor sensor, an outdoor
temperature of -5°C is simulated so that the house does
not get cold, and the product emits an alarm.
If a fault occurs with a room sensor, the EcoZenith
automatically switches to operating according to the set
curve, and the product emits an alarm.
