6.4.11.3 Extra regulation sequences 1 and 2
Used for extra regulation functions controlled by a 0-10 V (10-0
V) signal with ordinary temperature regulation sequence.
The function can be used for utilising existing heating or cooling
sources, such as from a chiller. The function can also be used for
an extra air heater or air cooler.
It can also be used for controlling dampers for recirculation, if
required. In these cases, an inverted 10-0 V output is used.
Recirculation control is used for the TBBD mixing section (GOLD
SD only) The 10-0 V inverted output should be in the On posi-
tion.
The maximum output signal can be limited from 100% down to
0 %.
The output signal of the extra regulation sequence is controlled
from the TBIQ-3-2 IQlogic
+
module accessory, see separate instal-
lation instructions.
When the SMART Link DX function is selected, the extra regula-
tion sequence is automatically activated. The extra regulation
sequence cannot then be used for any other functionality. An
IQlogic+ module is not required (alarm for missing module is
blocked).
The extra regulation sequence makes it possible to control two
air heaters at the same time in the following combinations:
water - electricity, water - water, electricity - electricity (Season
heat, see also Section 6.4.11.7). The air heater for hot water is
available without or without frost guard function.
When the output of the first air heater is not sufficient, the
second is automatically brought into the sequence.
A start-up sequence, frost guard function, pump control, post-
cooling for electric air heater and other functionality are avail-
able.
For the start-up sequence, frost guard function, periodic opera-
tion and post-cooling, the same settings are used as for regular
reheating.
