Caleffi iSolar Relay Controls
Differential Temperature Controllers for Solar Water Heating Systems
|
A multi-functional temperature differential controller with add-on system functions, the iSolar
series can be used for a wide variety of applications and has inputs for four PT1000 sensors. Preset
factory defaults are defined for control of a standard solar water heating system with a second
relay (some models) to divert any surplus heat. The auxiliary relay can be used to maintain the tank
temperature, protect the system from overheating, or use another source to heat the storage tank.
This controller features a large Liquid Crystal Dispaly (LCD) user interface with three function
keys. The easy-to-use icons assist to operate and customize a solar heating system.
