Pellas X S.Control User Manual

36
Circulation operation time
40 min.) Circular pump operates constantly during circulation operation
time. (recommended setting 60-120s)
Exchanger
Parameter available after activating option display advanced = YES.
It only refers to hydraulic installation with heat exchanger between
open and closed circuit, point 12.2. Available options:
 YES (boiler pump operates constantly in short circuit boiler –
exchanger, it is not excluded i.e. from SUMMER function or HUW
priority)
 NO (pump operates normally)
HUW heat source
The ability to choose a source of heat for the HUW tank - boiler or buffer.
14.4 BUFFER
Buffer support
Parameter serves to activating buffer operating mode. Available after
connecting additional module B and buffer temperature sensors.
Loading start temperature
Parameter buffer loading start temperature defines high temperature
below which buffer feeding starts. Buffer feeding proces is finished
when low temperature reaches value defined in parameter buffer
feeding end temperature.
Loading end temperature
Start heating system
The temperature below which the heating system is deactivated,
measured at the upper part of the buffer.
14.5 MIXER
Mixer support
 Off
Mixer serwomotor and pump are not active
 CH on
Applicable when mixer cycle powers heating installation of CH.
Maximum temperature of mixer cycle is not limited, mixer is fully
opened during alarms i.e. boiler overheating. Attention: do not activate
this option when installation is made of pipes sensitive to high
temperature. In such situations it is recommended to set mixer service
on FLOOR
 Floor on
Is used when mixer cycle powers floor installation. Maximum power of
mixer cycle is limited to value of parameter max preset mixer
temperature.
Attention: After choosing option FLOOR, it is necessary to set
parameter max mixer preset temperature on such a value to not
damage the floor and avoid scalding risk.
 Pump only
When mixer cycle temperature exceeds value set in parameter mixer
preset temperature, feeding of mixer pump is stopped. After
decreasing temperature of circuit by 2 degrees C – pump is
reactivated. This option is normally used to control floor heating pump
in situation when it cooperates with thermostatic valve without
servomotor. By such action is not recommended. It is recommended
to use standard heating cycle in floor heating, which consists of valve,
servomotor and mixer pump.
Thermostat selection*
Parameter available only after connecting to room panel Room
Control. This option allows change of room thermostat for mixer cycle.
Options available:
 Universal – standard thermostat connected to terminals 28-30 for
mixer 1, for mixers 2,3,4,5 use proper terminals in additional
modules.
 ecoSTER T1 – thermostat 1 in Room Control,
 ecoSTER T2 – thermostat 1 in Room Control,
 ecoSTER T3 – thermostat 1 in Room Control,
If Room Control is not connected then the controller cooperates
with standard room thermostat.
Minimum mixer temperature
Using this parameter it is possible to restrict Chance of setting to low
preset mixer circuit temperature. Automatic control (i.e. periodical
