Application The Ambient Air Humidity and Temperature Probes HT12 and HTF12 serve to continuously seize the relative air humidity and ambient temperature in housing space and business premises. The probes can be operated in connection with all Kieback & Peter regulators and regulation systems containing analogue 0..10 V entries and sensor connections for the active measuring unit KP10. As an additional feature, the set-point adjuster of the Ambient Air Humidity and Temperature Probe HTF12 enables the setting of the required ambient temperature.

Assembly The assembly of the combined Ambient Air Humidity and Temperature Probes HT12 and HTF12 can be wallmounting or buried wiring respectively. For a quick and correct detection of the room temperature the room probe shall be installed as to be able to detect the airflow in the room. The vent slots of the hood must be located vertically above one another. Airflow 1,5 m Correct for housing space and business premises False Assembly Instructions Connect the room probe in accordance with terminal connecting plan, position the hood and tighten the safety screw. Release safety screw and 1 take off hood. 3 Tweak for cable entry 60 The cardboard box serves as protective cover during the installation phase. For this purpose, please fold the side boards to the inside and rip off the box cover. M3 x 20 Tweak for cable entry from above 60 2 3,5 x 45 4 Page 4 / 8
Installation Danger Electric installation and probe connection shall be carried out by qualified experts only. Before connecting the Ambient Air Humidity and Temperature Probe to the regulation unit, the switchboard shall be switched voltage-free. In this context, the regulations of the VDE (Association of German Electro technical Engineers) as well as the local regulations shall be observed. The Ambient Air Humidity and Temperature Probes HT12 and HTF12 contain perforated bases and caps for connection purposes. These pieces can be tweaked out in order to insert cables.
