An electronic balancing relay from Control Ability is suitable for controlling air-conditioning systems via Thermister sensing elements. It is designed to compare two electrical signals and operate one of two relays when the signals differ by more than a preset amount.
There are two models, one operating from a 24V dc, the other from a 24V ac supply, and they are available either on a grp printed circuit board or completely enclosed in a splash-proof plastic enclosure. Made by: Control Ability, PO Box 42, Blackburn.
