Example
If Cooling abs. start is set to 24°C, the cooling unit will first start to operate when
the temperature exceeds 24°C, even though the daily user has set the required
room temperature to 21°C.
Menu 3.1.1.1.x - Heating absolute start
Definition
This value determines when heating must start in relation to the absolute tempera-
ture. Lower and upper limits are shown in the display.
Example
If Heating abs. start is set to 18°C, the heating coil will not start to operate until the
temperature falls below 18°C, even though the daily user has set the required
room temperature to 21°C.
Menu 3.1.1 - Operation settings - Temperature regulation
Select one of two temperature regulation methods:
● Supply air temperature regulation
● Room temperature regulation (temperature regulated until the desired level is
reached)
Temperature regulation is adjusted serially, using the following elements:
● Modulating heating coil(s).
● Any external cooling unit and cooling recovery
Select
Select one of the following:
●
Supply air regulation
- Typically used when the unit serves several rooms
with different loads (sunlight, people, machines). The temperature is regula-
ted by the built-in temperature sensor in the supply air spigot. If cooling
and/or heating coil(s) are fitted, temperature is regulated from the nearest
temperature sensor in the supply air duct.
●
Room temperature control
- Typically used when the unit serves several
rooms with similar loads. The temperature is regulated by the built-in temper-
ature sensor in the extract air spigot or via an external duct or room sensor
(accessory).
