TEMPERATURE ADJUSTMENT - INSTALLATION WITH LOOP
Example of normal "mixed water" operation WITH RECIRCULATION LOOP
VM1 - VM2 : micrometric valves to stabilise
the recirculation loop temperature
VM1A : open between 70 and 90%
VM1B : open between 30 and 10%

SETTING MODE
1 - Operate the circulator, and ensure that the temperature of DHW production is
greater than the set value of the loop.
2 -Go to setting mode
3 - Set the desired set temperature by successive press on
then validate by pressing
The e-Ultramix adjusts automatically for up to 5 minutes
(the LED of the actuator starts to flash after 15 s).
Stay on this screen and maintain flow rate for the duration of the adjustment.
The setting ends with memorization by switching to normal mode :
- automatically when the target temperature is reached, and returns to normal mode,
- either after 5 minutes and setting failure ---> start the cycle again.
You can stop the adjustment cycle during there running time by pressing
NORMAL MODE
Back in normal mode, the electric actuator is inactive, the regulation of the
temperature is mechanically controlled by the bimetallic strip.
