8.3 Room temp.

This is used to set the desired room temperature. Use

the plus and minus buttons to set the temperature

you want, which gives you the “setpoint” temperature,

shown in brackets. You can see the current value next

to the brackets.

If two radiator systems are installed, the values for both

are displayed.

If you want to schedule a temperature reduction,

you can continue to the Night reduction or Holiday

submenus.

You can select Room sensor No under the Installer/

Define system/Radiator system menu. This can be

done if the room sensor is awkwardly positioned, if the

floor heating control has its own room sensors or if you

use a fire place 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 the rooms in other parts of the house. The

room sensor can temporarily be deselected during

the firing process. The EcoZenith i250 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.

8.3.1 Setting a room temp. without a

room sensor

If a room sensor has not been installed (this can be

selected from the Installer/Define/Radiator system

menu), the room temperature is adjusted using

this option, which displays the setting range as a

percentage. (50) denotes default setting; the heat can

be increased or decreased in variable adjustments from

this value. If this range is not sufficient, the basic setting

must be adjusted under the Installer/Settings/Radiator

system menu.

Change the value in small steps each time (approx. 2

to 3 steps) and wait for the result (approx. one day), as

there is a delay in the system responding.

Several adjustments may be necessary at different

outdoor temperatures, but you will gradually achieve the

right setting that will not need to be changed.

The example above shows how it operates with two radiator

systems. Radiator system 1 with a room sensor and radiator

system 2 without one.
