8.3 Built -in sensor configuration

The CM67z Room Unit features a built-in temperature sensor used for specific applications. Sensor operation is defined by parameter 6:tS in Installer mode:

6:tS = 0 (Factory default. The built-in sensor is idle - not used for control nor measurement).

6:tS = 1 (The built-in sensor is used only for measuring the room temperature)

The symbol displayed next to the room temperature value indicates that the sensor is used for measurement only and the temperature in the room is controlled by the HR80UK Radiator Controller. Due to different locations of the CM67z Room Unit

and HR80UK Radiator Controller there may be a difference between the setpoint displayed by the CM67z Room Unit and the measured temperature value.

6:tS =2 (The built-in sensor is used to measure and control the room temperature in zone 1 or when a zone valve is used in zone 1) The CM67z Room Unit must be located in zone 1.

To complete the configuration you must set the 17:SU parameter to decide which system components will use the temperature value from the CM67z Room Unit:

17:SU = 0 - HR80UK's only (factory default)

17:SU = 1 - HC60NG (zone valve controller) only, HR80UK's will use their own built-in sensor.

17:SU = 2 - both HR80UK's and HC60NG.

8.4 Adding a HC60NG Zone valve controller

The HC60NG relay module can also be configured for controlling a zone valve. This is restricted to zone 1 only.

Before the binding procedure is started the following CM67z Room Unit parameters need to be set in order to control the zone 1 temperatures via the HC60NG as zone valve controller:

Enter the installer mode of the CM67z Room Unit and set the installer parameters: 6:tS =1, 9:Sn =1, 17:SU =1 or 2 (see Built-in sensor configuration).

9.2 Manual adaption

Manual adaption can be used to solve various problems:

• if automatic adaption does not work.
• if the entire valve lift is to be utilized.
• if the radiator hardly gets warm at all.
• if the radiator does not become cold.
• if the E symbol is displayed (no adaption possible).
• if the [3] symbol is displayed (valve lift too short or motor cannot be moved).

9.3 Def (default setting) and Full operating modes

In order to change between the two operating modes, press the 'binding button' until the respective operating mode is shown on the display.

Binding Button

Def (default setting) operating mode

The HR 80 operates with the optimum valve lift that is required for room temperature control.

Full operating mode

If the complete valve lift is to be used or if the valve does not close completely, you have to set the HR 80 to the full operating mode.

The battery lifetime is reduced in the full operating mode.

9.4 Resetting the HR 80 to the factory settings

• Separate operating unit from the coupling module (Fig. 1).
• Remove the batteries.
• Insert the batteries again while keeping the binding procedure button pressed.
• Attach the operating unit to the coupling module (Fig. 2).
