Description of possible operating conditions
Standard mode; automatic switch-over to night setback mode is
enabled. Night-time mode is activated at minimum heat output
requirement (default).
Pump runs in night-time mode (night setback operation) at min. speed.
Automatic switch-over to night setback mode blocked, i.e. pump runs in
standard mode only.
Night setback mode activated via interface Ext.Min, regardless of the
system temperature.
Pump switched on (default).
Pump switched off.
Differential pressure set value set to H = 18.0 ft. (example)
Control system Δp-v, regulated to variable differential pressure set
value (fig. 6) (default).
Control system Δp-c, regulated to constant differential pressure set
value (fig. 7).
The regulator mode control system deactivates the module pressure
variations. The speed of the pump is kept at a constant level. The speed
is set internally using the tuning button (fig. 9).
Pump set to a constant speed (2.600 rpm example shown) - regulator
mode.
In regulator mode, the speed or nominal lift of operating mode Δp-c or
Δp-v of the pump is set via input 0...10 V of the Stratos IF module
Ext.Min. The button then has no set value input function. (fig. 10)
Control system Δp-T, regulated to temperature dependent differential
pressure set value (fig. 8). The maximum set value Hsmax is displayed.
This control system can only be activated via the IR module.
All settings on module except "acknowledge error" blocked. Settings
locked out by IR module. Settings can only be altered using IR .
Pump runs as slave pump. No changes can be made to the position
setting of the display.
Two single pumps as double pump running in peak load mode (master +
slave)
Two single pumps as double pump running in duty / standby mode
(master or slave)
Subject to technical alterations!
