aqualisa opto t e

The unit i've been asked to look at runs off a combi boiler and apparently sometimes suddenly runs hot and sometimes cold . The installation guide suggests the supply pressure may be too high . I will try this but if you have any further suggestions i would love to hear them . Many thanks. Duncan.

This is due to what we call a "cycling boiler " and this is where to start.
