10.1.3. Temperature control (DI and DC versions)
In models with post-heating (DI and DC), the Termo-Reg unit performs temperature control.
For this purpose, depending on requirements, the opening or closing of the By-pass and the
use or not of the post-heating battery is managed.
First priority is given to reach the temperature set by opening or closure of the By-pass. In
case of if not suffi ciently proceed activation of the post-heating battery.
The temperature taken as reference control is selectable
between supply temperature (contribution to local) and ex-
traction temperature (indoor environment). (See settings in
installer mode)
By default, the control is set to control the supply tempera-
ture (contribution to local).
By pressing the TEMPERATURE button is possible choose
between low, medium or high temperature.
An LED indicates the selected temperature.
The user can select 3 different levels of temperature inside of a certain range of values. There
are 3 ranges of temperature: ºC 17/20/23, 20/23/26 and 23/26/29ºC. By default, the predefi ned
temperature range is ºC 20/23/26. To change this temperature range must be accessed in
installer mode.
To turn off the heating mode, press the TEMPERATURE button until all 3 temperature leds
are off.
10.1.4. Drive By-pass
The By-pass function allows (By-pass closed) or by-passes
(open By-pass) the passage of air through the heat exchanger.
The By-pass has two modes of operation:
•
Manual: The By-pass can be selected to always remain
open or closed.
• Automatic: In this mode the control will decide, depending
the values of the various temperature sensors and tem-
perature setpoint, whether open or close the By-pass as
there is demand for warm or cooler air. Below 15ºC the
By-pass will always remain closed to prevent low supply
temperatures.
