3.8 CBE-EM DUAL ENERGY
INSTALLATION
Your DTH boiler can be hooked up to an existing
oil or gas boiler.
The CBE-EM-SV dual-energy control is specially
designed for those applications. The CBE-EM-
SV control selects the least expensive energy
source,either oil or electricity based on user
manual choice or a contact from an external
controller. The DTH boiler is equipped with an
external terminal block facilitating the connection
between the two units.
In “Oil Mode” The CBE-EM dual-energy control
will start up the oil burner upon receiving a
demand signal. It will shut off when the
temperature in the boiler reaches its target on
the Limit Control or when the heat demand has
been satisfied.
In “Electric Mode” the electric boiler is activated
and will maintain its temperature hot at the
temperature selected on its aquastats always
ready to distribute heat to the heating system.
When the temperature of the boiler will drop, the
heating elements will come on.
