Cooling circuit control
93
Output variables
Set flow temperature
Issue of the current set flow temperature
Effective set room temp.
Issue of the effective (= current) set room temperature
Clg circ. pump
Cooling circuit pump status ON/OFF; selection of the output
Open/close mixer
Mixer status OPEN/OFF/CLOSE; selection of the switching outputs
(dual output)
Mixer 0 - 100 %
A percentage value to one decimal place, for control of a mixer with 0-
10 V input via an analogue output (O12- O16)
Derivative time
The effective derivative time subject to outside temperature
T.room > set
Status OFF if the shutdown condition Act. T.room > set is met.
T.outside > min.
Status OFF if the shutdown condition T.outside AVo < min. is met.
T.flow > min.
Status OFF if the shutdown condition Act. T.flow < min. is met.
Remaining runtime ctr
Display of the remaining mixer runtime
Mixer open
Status ON when the mixer is fully open (after expiry of remaining
runtime)
Mixer closed
Status ON when the mixer is fully closed (after expiry of remaining
runtime)
Average OT for shutdown
Calculated adjusted outside temperature, utilised for the pump
shutdown conditions (see Average sub-chapter)
➢ If the cooling circuit pump is switched off by the time condition status, then the set flow
temperature is issued as +200 °C and the effective set room temperature as +50 °C.
If the cooling circuit pump is switched off by means of the Window contact or a
Shutdown condition, only the set flow temperature will be issued set to +200 °C.
➢ Mixer 0 – 100 %: Scaling of the analogue output: 0 = 0.00 V / 1000 = 10.00 V
➢ The remaining runtime counts down from 20 minutes when a dual output (mixer drive) is
linked to the Open/close mixer output variable. If a dual output is not linked, the remaining
runtime counts down from 2 minutes.
➢ If the runtime limit was deactivated in the mixer output settings, the remaining runtime
only counts down to 10 seconds and output pair control is not terminated.
➢ The remaining runtime (20 minutes) is reloaded if the mixer output is in manual mode, is
switched by a message (to dominant ON or OFF), changes its direction of control from
OPEN to CLOSE or vice-versa, or if Enable is switched from OFF to ON.
➢ Mixer open / closed: If the runtime limit was deactivated, the mixers are still displayed as
open or closed after the renaming runtime is complete.
➢ The output variables that refer to shutdown conditions are always in status ON if the
applicable shutdown condition has not been activated.
