Circulation Pump; (Solar Thermal System Coupling Kit) - Immergas SUPER TRIO Instruction Booklet

1.37 CIRCULATION PUMP (SOLAR THERMAL
SYSTEM COUPLING KIT).
The units are supplied with circulating pumps fitted with speed
regulator.
These settings are suitable for most systems.
In fact, the pump is equipped with electronic control to set ad-
vanced functions. For proper operation one must select the most
suitable type of operation for the system and select a speed in the
available range, with a focus on energy savings.
Display of operation status (Fig. 64). When the pump starts,
the LED (2) lights up green for about 2 seconds, followed by
short flashing at great intensity to then switch off during normal
operation. The LED (3) only lights up in PWM setting, not used
in the application. The three yellow LEDs (4) indicate the three
constant curve speeds.
Selection of operating mode. The operating mode is always visible
and indicated by the 3 yellow LEDs (4).
Info: All the LEDs are off when the pump is not powered.
Press the button (1) to change operating mode.
Every time the button is pressed, all the possible functions are
scrolled cyclically according to the following table:

- Constant curve: the pump works maintaining system head con-
stant. The pump working point will move up or down according
to the system's demand.
- PWM Profile: Do not use this operating mode.
Attention: if this profile is selected, the pump will stop.
For the Super Trio, the pump is set at "Constant curve speed 3"
by default.
Real time diagnostics: in the event of malfunction the LEDs pro-
vide information on the pump operation status, see table (Fig. 65):
Key:

3 - Green (G) LED
4 - 3 yellow (Y) LEDs
Diagnostics
The circulator pump cannot restart
automatically due to an anomaly
Voltage off range
The circulator is locked due to power
supply too low or serious malfunction

Remedy
Wait for the circulator to make automatic
release attempts or manually release the mo-
tor shaft acting on the screw in the centre of
the head.
If the anomaly persists replace the circulator.
Check power supply
Check the power supply, if the anomaly persists
replace the circulator
