5.10 Application
The section "Application" describes specific application related
issues.
"Total stop" (ID 1x021) works differently, depending on actual
subtype. In relation to the parameter "Fan function" (ID 11137),
selected subtype and controller mode, different functionalities are
present. See the related tables.
"Stop at T out" (ID 1x038) is used for the "Night cooling" function.
Outdoor temperature must be higher than set value in order to
activate "Night cooling".
"Comp. T select" (ID 1x140) is a universal parameter:
A214.1 - A214.6 and A314.1 - A314.3:
The desired flow / duct temperature can be influenced by a
compensation temperature, measured by S1 or S2. The choice
between S1 and S2 is made by the parameter "Comp. T select".
A314.4 - A314.7 and A314.9:
The desired flow / duct temperature can be influenced by a
compensation temperature, measured by one of the temperature
sensors S1 . . . S16.
The choice of compensation sensor is made by the parameter
"Comp. T select".
"Summer, cut-out" (ID 1x179) is present in A314.4 and A314.5.
When outdoor temperature gets higher than cut-out value + 0.5 K,
the heating is stopped.
Falling outdoor temperature: When actual - and "accumulated
outdoor temperature" come below cut-out value - 0.5 K, the
heating will start. The time constant for "accumulated outdoor
temperature" is a fixed value and corresponds to an average
building's time constant.
The parameter 'Stop difference' (ID 1x194) is used differently,
depending on application:
A214.6: When X3 is set to act as room thermostat.
A314.4 … A314.7: When utilizing the "Night cooling" function.
The room temperature must be "Stop difference" higher than the
outdoor temperature for enabling "Night cooling".
"S4 filter" is present in the subtypes A214.2, A214.4 and A314.1.
"1. step level" and "2. step level" are used for smooth transition
between recovery stage and heating / cooling stage.
"Send desired T" (ID 1x500) is present in some of the subtypes.
Parameters indicated with an ID no. like "1x607" mean a universal
parameter.
x stands for circuit / parameter group.
