EKCO.T consists of the following
main parts:
- a heating box [3] to heat the
circulating medium,
- a control board [14],
- a circulating pump [12] to
force water to flow.
There are safety devices to protect
the boiler from failures and destruc-
tion:
- a safety temperature limiter [6],
cuts off power supply if water
reach temp. of 100
0
C, as a
result of it the boiler will shut
down (contact an authorised
service),
- a flow sensor [8], starts the
boiler if the correct flow is
reached,
- a safety valve [9] activates
if the pressure in the central
heating system goes over the
pressure limit (3 bar).
