Hi,

Bought a house a year ago with 3 thermal panels on the roof that heats the hot water 100% between April-Sept. It has a Glowworm Clearly Solar controller which has now died. 240v incoming and fuse is intact but readout is dead so not activating pump therefore no hot water. Research so far indicates that the system is obsolete and no-one has the controller in stack.

Can you please recommend a replacement controller that would show the panel temps (flow and return)?

Thank you.
