EHC20

The EHC20 is an intelligent control for your exodraft solution for heat recovery. If the temperature exceeds the desired level on the water side, the EHC20 secondary flow valve opens in the heat recovery unit and directs the flue gas/vapour directly into the chimney.

As a result, overheating is prevented and a safe operation is ensured.

The EHC20 also controls a 3-way mixing valve, which ensures that a circulation to the collection tank occurs when the water has reached the desired temperature.

If the water does not have the desired temperature, recirculation takes place to the heat exchanger until the desired temperature is reached.

Description

Overview of your energy savings

You can constantly read how much energy is recovered via the heat exchanger. This way you can see the results of your investment. If the heat exchanger is unable to reach the desired temperature in the accumulator tank, the EHC20 can control an additional heat source, which can be started/stopped as required.

Quick set-up with the Startup Wizard

The EHC20 is equipped with a display that allows you to easily read and configure the values of your heat recovery system.

The EHC20 is equipped with a Startup wizard for simple installation with which the most important functions can be configured, and from which eight predefined system setups can be selected.
