Using the PH-BHD in PocketHome®system:
Using the PH-BHD in autonomous system:
Objects with their own heat sources (eg family house)
Central unit PH-CJ37 plus control receiver of boiler PH-PK20 (PK21) in accordance with the requirements of the
various rooms in which are located control unit PH-BHD (which measures the temperature of the room). If in any of
the room (with assigned priorities) the temperature drops below the required level controller PH-BHD sends a request
warheads to open the valve. Subsequently, the central unit PH-CJ37 plus provide power to the boiler and heating of
the room. PH-CJ37 Plus you can activate up to 99 controllers PH-BHD ---> allows you to extend the system for larger
buildings within reach!
Objects without any heat source (flat with central heating)
Control unit PH-BHD measured of temperature in the reference room, where it is located. When the temperature
drops below the required level sends instructions to all controllers to open the valve. All controllers PH-HD01
(PH-HD20) work as one temperature program to set PH-BHD. This system is suitable for smaller objects.
In conjunction with the GSM module it is possible to operate the system remotely, using a mobile phone!
