8.4 Characteristic curve temperature sensor outdoor unit
8.5 Characteristic curve temperature sensor indoor unit
8.5.1 Sensor characteristic curves
The temperature sensors to be connected to the heat pump
manager must correspond to the sensor characteristic curve il-
lustrated in Fig.8.1 on pag. 16. The only exception is the out-
door temperature sensor included in the scope of supply of the
heat pump (see Fig.8.2 on pag. 16)
Fig. 8.1: Sensor characteristic curve NTC-10
Fig. 8.2: Sensor characteristic curve NTC-2 according to DIN 44574
Outdoor temperature sensor
8.5.2 Mounting of the external outside
temperature sensor (optional)
With outside temperature based control, the connection of an
outside temperature sensor (FG 3115) is recommended for
mounting on the north side of the building, as incorrect values
would otherwise be recorded for the heating curve calculation
(e.g. during intensive sun radiation).
The external sensor (FG3115) is connected to the heat pump
manager and activated by after-sales service during commis-
sioning.
With room temperature based control via the smart RTC, no ad-
ditional outside temperature sensor is required.
