INSTALLATION NOTES
The installation and, if necessary, the maintenance and the disassembling must be
carried out by a qualified electrical installer.
The installation must be compatible with local regulations.
check the maximum circuit length for your circuit breaker in the next table:
Maximum circuit length at 230 VAC and for 20°C start-up temperature

.
Multiple units on multiple power points can be used if longer heating cables are
required. We recommend to use compatible

The
Domotec DHB 370 C Therm-Control
has a removable top lid. Both top and bottom of
the box have electronic parts and are connected to each other by an Ethernet connector
cable. the unit is delivered with top lid and back part dismantled.
Warning:
f
or over voltage protection (e.g. in case of thunderstorm) we recommend
the use of an external over voltage protection device.

C
lean the Hwat-Eco with a soft damp cloth only, do not use any solvents. do not pour
water directly on the device. do not use a water hose or a high pressure cleaner.
3.1. Description
T
he
DHB 370 C Therm-Control
unit has been developed for operation with the
self-regulating heating cables
Domotec DHB 200
.
T
he hot water temperature maintenance system is a comfort system providing instant
hot water at the tap.
A
self-regulating heating cable is positioned on the pipe and
compensates for any temperature loss of the warm water.
T
he
Therm-C
ontrol unit combines the following features:
•
T
he operating temperature of the heating cable can be limited to a desired
temperature. combined with the integrated “power off” timer function, this offers
important energy savings.
•
Energy can be saved upon activation of the “trace
water heater
” function and
installation of the boiler sensor.
T
he maintain temperature of the heating cable will
automatically be lowered in case the
water heater
temperature is reduced,
preventing the heating cable from using too much energy for heating the water in
the pipes.
•
O
n big warm water systems it is sufficient to programme one
Terh-Control
unit
in SBS panel to manage multiple heating circuits. The
Therm-Control
controller can
be delivered in different prefabricated panels, depending on the quantity of heating
circuits (3, 6, 9).
•
A
n alarm terminal makes remote reading of errors possible.
•
A
pipe sensor (to be ordered separately) can be installed as reference point to track
and monitor pipe temperature in a large hot water distribution network.
•
T
he unit can be pre-programmed in power-off mode by external power bank
(to be ordered separately) connected via
