14. AUXILIARY CONTROL

If detector B5

is not connected and not configured

, output M2

can be used as a time switch with programme chosen in

If detector B5

is connected but not configured

it functions only as a temperature monitor

If detector B5

is connected and configured

the auxiliary control, according to programme chosen in

compares the temperature measured with desired temperature set in

and produces the On-Off control action of output M2 according to temperature difference and

parameters set :

•

Diff : – – . – c

= On-Off stage differential

•

Prop band : – – . – c

= proportional band in ± °C

•

Integ time : – – m

= integral time in minutes

•

Half cycle time – – – sec

= start and stop time when actual temp. is equal to desired temp.

14.1 Control output M2

The start and stop controls of output M2 depend not only on the control parameters set but also on :

•

Minimum start time : – – sec

= minimum start time

•

Minimum stop time : – – sec

= minimum stop time

•

Delay Off

: – –

min

delay time in switching off : when output controls pump of a primary zone

and boiler is controlled, via C- Ring, by maximum temperature requested by zone controllers,

this permits dissipating residual heat in combustion chamber.

14.2 Operating mode

The

Desired Aux temp

is used in establishing the three programmes of timed events 24 HOUR 1 …3

AUX which , in turn, are used to establish the 7-day programme 7DAY AUX.

It is possible to programme the operation of the auxiliary control according to the requirements of

the zones :

–

7 DAY AUX

= in operation 7-day programme with timed events

– 24 HOUR 1 …3 AU

X = in operation one of three 24-hour progs. with timed events

– ON

= continuous operation at

Desired Aux temp

– OFF

= always Off

The current

operational mode

depends on programme set

• Pri mode :

= mode set by programme

– ON

= control by

Desired Aux temp

– OFF

= control Off

• Td 20.0 c = temperature desired by current mode

• Var +

0.0

c = manual adjustment of desired temperature (use + or – keys)

max ± 10 °C.
