10 EE03 Humidity and temperature Module
EE220 basic unit can accommodate also the EE03 humidity and temperature module. EE03 is
dedicated for the measurement of surface moisture and for detecting the danger of condensation
on a surface before the condensation actually occurs.
For technical details, ordering guide and mounting accessories see the EE03 data sheet.
Connect EE03 to the first (left) probe socket of the EE220 using the cables HA010328 or
HA010329. EE03 cannot be plugged directly onto EE220. For accurate surface RH
measurement the T of the EE03 shall be the same as the surface T, so it is of paramount
importance to assure best thermal contact between EE03 and the surface to monitor.
EE03 can be adjusted neither together with the EE220 basic unit, nor individually. With EE03
connected, the S1 and S2 push buttons have no function. An EE03 deemed faulty shall be
replaced against a new one.
11 Replacement of the Probes
A damaged probe can be replaced by a new one without any EE220 setup change or re-adjust-
ment, as follows:
1. Switch off supply voltage
2. Remove faulty sensor probe
3. Plug in the replacement probe
4. Switch on the supply voltage
Important: Do not mix up the position of the probes! (see chapter "4.2 Connecting the EE07
sensing probe")
12 EE220 Display Replacement or Retrofit
If needed, a damaged EE220 display can be easily replaced by the user. Furthermore, an EE220
without display can be easily upgraded to an EE220 with display.
The EE220 display is available as spare part. The scope of supply includes the display, the front
cover of EE220 (plastic or metal) and a quick user guide.
The ordering numbers for spare EE220 display are:
• D07P
• D07M
1. Remove the EE220 front cover.
2. Switch of the power supply or plug off the EE220 screw terminals on the main electronics
board.
