User manual HONEYWELL HR80

[. . . ] The correct installation of the coupling module is best checked with the central heating switched on. As the valve is a self contained unit, there is no risk of it causing any water leakage from your heating. Manually using the adjustment dial on the operating unit of the radiator controller · With the command centre The radiator controller communicates with the central operating unit via a wireless connection. [. . . ] Failed binding procedure The binding procedure has failed if the symbol extinguishes. Take the following measures: If the symbol extinguishes during normal operation, possible causes are discharged batteries at the command centre. You do not have to repeat binding operation, if the communication is reestablished. If you remove the batteries and insert them again, the HR80 goes direct in sync mode. Pull operating unit and coupling module apart from each other Counterclockwise until the nose (1) of the adjustment dial is positioned at the stop (2) of the housing (Fig. In order to change between the two operating modes, press the binding procedure button (1, Fig. The HR 80 operates with the optimum valve lift that is required for room temperature control. 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. Before screwing the radiator controller onto another valve: Separate the valve lantern from the operating unit. Every local change in the setpoint temperature remains valid until a time program overwrites it automatically. Insert the batteries again while keeping the binding procedure The set temperature is controlled by the command centre and set there as well. For further information please refer to the operating instructions of the command centre. 1 Changing set temperature with adjustment dial Turn the adjustment dial of the operating unit until the desired set temperature (between 5 ­ 30 °C) is displayed. The range for the set temperature (standard range: 5 ­ 30 °C) can be restricted at the command centre. In order to open or close the radiator valve completely: Turn the adjustment dial until "OFF" (closed) or "ON" (opened) is displayed. (If temperature limits are set, "ON"/"OFF" is not displayed. If the symbol e3 is shown on the display, the motor of the HR 80 can no longer be moved. The following adapters/coupling modules are available for Oventrop, Herz, Danfoss, Vaillant and Caleffi valves: Coupling module type Order name Oventrop HU 01 (Fig. [. . . ] The radiator controller is ready to receive the test message from the command centre. The first two digits in the display indicate the number of received test messages, and the right-hand digit indicates the field strength (1 = sufficient field strength, 5 = very good field strength) To deactivate Service mode: Press the binding procedure button for 5 seconds or wait 5 minutes or remove and then reinsert the batteries. If the temperature drops below 5 °C, the radiator controller keeps the radiator valve at a constant 5 °C. [. . . ]
