NEW UPDATES RELEASE 1.06

• Broken outdoor temperature sensor halts the heatpump

As the break to outdoor sensor occurs, the outdoor temperature is shortly

interpreted as very high, placing the heat pump in ’Heat stop’, thus blocking it

from runnig until the deactivation time limit has run out. This issue has been

fixed.

• Webpages on controller don’t automatically update.

The webpages on the controller didn’t automatically update. Webpages will

automatically update according to set time with this release.

• New alarm; ’Master conflict’

If two or more heatpumps are connected as masters, a communication

problem arises between connected slaves, cooling and expansion modules.

Alarm ’Master conflict’ will indicate this problem.

• Modbus

Communication protocol Modbus has been implemented in this release in

order to connect the DHP-R to supervisory control systems.

Modbus is connected to RS232-port on the WM HPC. A new menu, ‘Modbus’,

has been added to ‘SYSTEM SETTINGS’.
