CB500 Control box (5 zones) 230 V


The CB500 control box is the main element of the underfloor heating / cooling control system. It has a built-in module that controls the heat and cool sources. The control box allows to control 5 different zones. Number of controlled zones can be increased up to 15 zones by using additional CB500X extension modules (CB500 main control box + two CB500X extension modules).  The CB500 has voltage-free outputs designed to control a boiler, heat pump or chiller. It allows you to switch between heating and cooling modes. It is equipped with 230V voltage outputs for a pump and actuators. The spring clamps provide quick and convenient wiring connections. The control box is designed to work with NC (normally-closed) type actuators.

Really helpful company, easy to deal with, no pressure selling and seem to know everything when it comes to heat pumps. They explained everything we needed and how it would work simply for us to understand.

We have just had our boiler replaced with a Cool Energy invertech heat pump. From initial enquiry through to recommending a local installer, we cant fault the service. The heat pump is very quiet and so far seems very efficient to run. Very happy!
