The Domotec Frost-Control DHB 360 C 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:
For over voltage protection (e.g. in case of thunderstorm) we recommend
the use of an external over voltage protection device.
Careandmaintenance
Clean the Frost-Control 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.
Avoid installing the controller in rooms with high humidity and condensation. To
operate the user interface, it must be clean and dry. For outdoor installation it will be
recommended to use a sun & rain cover.
Description
Domotec Frost-Control DHB 360 C is an electronic control thermostat with display,
advanced alarm facilities and the capability of switching large currents (25 A). The DHB
360 C is designed to control Domotec heating cable systems. Heating cable can be
controlled (switched ON/OFF) either directly by the Frost-Control or via a contactor.
Direct switching of heating cables is possible for heating loads up to 25 A.
For heating loads above 25 A indirect switching via a suitably rated contactor con-
trolled by a Frost-Control is necessary.
Installation and all wiring must be in accordance with applicable regulations.
The device must be installed in non hazardous areas only. Domotec offers other
controls for use in hazardous areas.
The sensor must be installed. Attention: The sensor position on pipe or in Air
needs to match the operation mode PiPE or Air. (PASC / ambient temperature
measurement control). A wrong assignment can led to a frozen pipe.
An alarm terminal makes remote signalling of errors possible. During commissioning of
the unit it is recommend to simulate sensor functionality in PIPE sensing mode, since
the AIR/PASC mode is not suitable for this test due to delay in the PASC algo-rithm.
The unit can be pre-programmed in power-off mode by external power bank (to be
ordered separately) connected via A-A-USB cable and USB connection.
