The iSolar MX LTE is a multi-functional temperature differential controller with add-on functions for use in a wide variety of solar thermal applications.

It’s equipped with five relay outputs including four triac pump-speed control relays and one dry contact relay; a 0-10 V pump speed control signal serves new high-efficiency pumps.

Eight Pt1000 sensor inputs, one CS10 irradiation sensor input and one impulse flow meter input provide for built-in accurate heat energy metering.

The controller comes complete with five Pt1000 sensors and one 0-10 V adapter cord. Twenty predefined system arrangements are configured for control of standard solar water heating systems, drain back systems, multiple storage tanks (up to four total), heat dump, storage tank booster heating and many others.
