22. CONTROL OUTPUTS
22.1 Control output Y
Outputs Y can be configured as:
• Y - MODULATING= modulating control for 3-wire valves or 3-wire
signal converters into 0...10 V– or step
controllers.
2 STAGES = 2-stage On-Off control (1 ; 1+2) for solenoid
valves, pumps, humidifiers, burners,
refrigerators, 2 equal-load electric batteries,
etc.
3 STAGES = 2-stage On-Off control (1 ; 2; 1+2) for 2 unequal-
load electric batteries.
• Stroke time: xxx
s =
valve actuator stroke time. It only appears if control is MODULATING.
Output Y must be assigned the type of action (load) which it must perform. E.g.: Heating.
If Season Switching is enabled in M3
.2, a different action can be assigned for each season.
E.g.: Y – Win: Preheating; Y – Sum: Cooling.
• Y - .....: PREHEAT = Preheating QPre
HEATING = Heating QHea
HTP HEA = Heating through heat pump Q
Hea.P.Cal
COOLING = Cooling Qcoo
FROSTPROT.= Frostprotection Q
frp (antifreeze control through one valve controlled
by another controller)
OFF = Not used in current season
22.2 Mu adiabatic humidifier control output
Output Mu (8-9-10) uses the Qhumi load to control the adiabatic humidifier:
While operating :– when setting is ON (only if the fan control Mv is on,
and only in Winter
if season switching is activated)
Off : – when setting is OFF
– in Summer, if season switching is activated
– when setting is ON, if the fan control Mv is off,
due to antifreeze temperature (B7)
22.3 Mv fan control output
The system’s fan Mv (output 13-14) is
:
On : – when setting is ON
Off : – when setting is OFF
– when setting is OFF : when load value Qfrp exceeds 10%, due to antifreeze temperature (B7)
22.4 Mp pump control output
The system’s pump Mp (output 11-12) is
:
On : – when setting is ON
– when setting is OFF : when load value Qfrp exceeds 10%, due to antifreeze temperature (B7)
Off : – when setting is OFF
