One or two point adjustment for RH and T of the transmitter can be easily performed with push buttons on the electronics board of the EE220 basic unit. Alternatively, the EE07 probes can be adjusted individually with the EE-PCA Product Configuration Adapter (see EE07 data sheet). -
Page 6: Installation
In order to avoid misreading caused by self-heating, the device shall be installed with the probes pointing downwards. In very humid, condensing environment it is recommended to use the EE220 version with remote probe, please see below. Operating instructions for EE220 humidity / temperature transmitter... -

(14 °F) (59 °F) • The adjustment data is saved into the EE07 probes. The EE220 basic unit is not affected by the adjustment procedure. Consequently, it is possible to replace the probes at any moment. • Start the adjustment procedure with the low point (e.g. 30 % RH) and continue with the high point (e.g. -

The set includes a test report for each reference probe. For EE220 basic unit dedicated for only one combined EE07 RH & T probe, both RH and T check shall be performed with each reference probe connected at the single probe connection socket. -
Page 12: Ee220 Check Using The Display
If the EE220 basic unit features a display, as soon as the reference probe is connected the display shall show the corresponding RH and T reference values. If the EE220 basic unit does not feature a display, it is easily possible to plug in a display (see chapter “12. EE220 Display Replacement or Retrofit”). It is highly advisable to keep a spare display specifically for this purpose or for easy adjustment of the entire EE220 including EE07 probes (see chapter “8.2. -
