5.2 SETTING OPERATION PRESSURE
The pressure setting of the MEC 18 must be adjusted to
assure proper pressure for the appliance.
The display (Fig. 13-C) has two functions. It shows what the
pressure set-point is, and it shows what the actual pressure is.
The default mode shows the actual pressure. To change the
mode, the set-point button must be pressed continuously.
To adjust the pressure set-point follow this procedure:
Temporary adjustment of the pressure:
1. Press the set-point button continuously with a pen or
screwdriver (Fig. 14-A) until the pressure setting appears
on the display. While continuing to press the set-point
button, use the potentiometer (Fig. 14-B) to set the
required pressure in WC/Pa on the display (Fig. 14-C).
Release the set-point button; the actual pressure will now
show up on the display.
2. Start the heating system and wait until the thermostat (Fig.
15-A) closes and the pressure has stabilized (none of the
yellow diodes are lit).
Final adjustment of the pressure:
3. Check the pressure at the appliance outlets and make
any necessary adjustment by following the procedure
described under step 1 above.
4. If used, check that the safety system disconnects the
appliance (Fig. 15-B). An error can be simulated by
disconnecting the silicone tubing from the negative port
on the transducer (XTP).
5. Check the start function after the final pressure setting
adjustments have been made.
