4.3.3 Automatic operation
For the dehumidifier to operate in Auto 1 or 2, the humidistat must be connected to the humidistat socket of
the unit, see section 3.10, Connecting the humidistat .
1. Reset measurement of power consumption as required, see section 4.3.1, Measured values .

3. Switch the on-off switch to position I, see
Figure 4.1 .
4. Select the Auto 1 or 2 operating mode by pressing the operating mode selector button, see Figure 4.1 .
NOTE! Connection of the humidistat activates a built-in 2 minutes delay function for re-start. The opening and
closing of the humidistat circuit within the 2 minutes period will not start the dehumidifier again because of the delay
function. In case the humidistat circuit has been opened for more than 2 minutes and then closes, the dehumidifier
will start immediately. The purpose with this function is to prevent the circuit from continuously cycling on and off, in
case the humidistat is installed in a poorly choosen location.
