Energy saving functions:
Ventilation
Savings potential for Ventilation
We assume a plant with 2-speed fans, heating, cooling and heat
recovery for the following function extensions.
– Indoor air quality (B) is demand controlled.
– Fans (A) for indoor air quality operate only when indoor air quality
limit values are exceeded.
– Room temperature (C) is demand controlled.
– Fans (A) for room temperature operate only when temperature
limit values are exceeded.
– Maximum Economy Changeover (MECH) (D) is implemented.
– Heat exchanger is monitored for efficiency (D).
– Night cooling (E) is implemented.
c
Demand-controlled by indoor air quality (pg. 17)
d
Demand-controlled by room temperature (pg. 19)
e
Maximum Economy Changeover (MECH) of heat recovery (pg.
22). Monitor efficiency of heat recovery system (pg. 21)
f
Night cooling (pg. 23)
• The energy saving functions depicted represent a selection of
available functional extensions for Synco ventilation controllers.
• For their part, the configurations of the functional extensions
described may represent a variant of multiple possibilities.
Please consult referenced documents for alternative
configurations.
• Setting parameters must be checked on a plant-by-plant basis.
• Supplemental configurations are not described; they may,
however, be derived from the plant diagrams.
