User manual HONEYWELL HCE 80

[. . . ] A maximum of 5 temperature zones can be set for each underfloor heating controller. This number can be increased to 8 by using the expansion module HCS 80. Take the 52 mm installation height of the underfloor heating controller into account. If the underfloor heating controller is installed at a severe angle, the transformer must be on top to allow for ventilation. [. . . ] Connect the pump in accordance with the following graphics (see the fold-out page, Fig. During commissioning, setpoint adjusters ­ and the time programs of the radio setpoint adjuster CM67z if applicable ­ are assigned to the temperature zones of the underfloor heating controller. A room name is defined for each temperature zone at the Hometronic Manager. The underfloor heating controller switches back to normal mode automatically after 60 seconds. Switching between heating and cooling is carried out via the changeover contacts 3 and 4. The signal strength of the radio transmission can be checked for the transmitter and the receiver. Repeat the steps until two room names are assigned to all the temperature zones. Green Off Thermal drive opened Thermal drive closed The various faults are indicated by the zone LEDs in fault mode. The following section explains how you can assign the various components to a temperature zone and allocate room names if a Hometronic Manager is used. If a room temperature sensor HCF 82 is combined with a remote setpoint adjuster HCW 82, i. Assigned to the same zone, first assign the remote setpoint adjuster and then the room temperature sensor. The device display shows which devices are assigned to the underfloor heating controller. If the underfloor heating controller is used as a cooling regulator, this function has to be activated once during installation. LED lights up green Cooling mode active Heating mode active LED lights up red Change the setting by pressing the installation button In order to assign the setpoint adjuster to a different zone, press the installation button until the LED of the desired zone flashes red. Information about the parameter settings of the CM67z can be found in the corresponding operating instructions. Move the slide switch at the operating unit CM67z to the position OFF. Move the buttons TEMP , TEMP and PROG 1 together in order to activate the teach-in mode for Zone 1. In order to assign the CM67z to a different zone, press the installation button until the LED of the desired zone flashes red. Repeat the steps until a room name is assigned to all the temperature zones. The assigned temperature zones remain stored in the underfloor heating controller, even after a power failure. You have to assign an external sensor (HCF 82) to the zone (see Allocating the setpoint adjuster HCW 82, room temperature sensor HCF 82, chapter 8. Move the slide switch at the operating unit CM67z to the position OFF. [. . . ] After the underfloor heating controller has been commissioned, inform your customer about the heating control system. explain the function and operation of all the components to the customer. Point out particular features to the customer and ensure that they are aware of the possibility of expanding their system. The underfloor heating controller retains its configuration after a power failure. [. . . ]
