Emergency valve opening
It is a % valve opening during active boiler overheating
alarm. This parameter is used for cast-iron boilers, and is
available in some regulators only.
Proportional range
This parameter influences the range of mixer servo motion.
Increase of its value causes actual mixer temperature
reaches faster the preset value, but too high value set
causes temperature overshoot and unnecessary servo
motions. Correct value should be determined
experimentally. Recommended settings of this parameter
should be within the range of 2 – 6 [3].
Integr. time const.
The higher the value of this parameter is the slower the
response of servo on temperature off-set is. Setting too low
value may cause unnecessarily servo motions, while too high
setting will increase time of finding preset temperature
value. Correct value should be determined experimentally.
Recommended settings of this parameter should be within
the range of 100 – 180 [160].
15 BUFFER
Buffer Support
Switches ON/OFF buffer support.
Buffer loading start temp.
Temperature measured by upper buffer sensor at which
buffer loading starts.
Buffer loading end temp
Temperature measured by lower buffer sensor at which
buffer loading ends..
Min. buffer temp.
Temperature measured by upper buffer sensor at which the
pumps are switched off and the mixer servos are closed.
Note: these parameters are available upon connection of additional module B.
16 Output H
Output H
This parameter determines the function being executed at
Output H (terminals 30-31). Following options are available:
- Reserve boiler;
- Alarms;
- Circulating pump ;
- Boiler Shunt Pump ;
