CLIMATE PROFILES

EWHT800LX manages curing cycles by means of climate profiles consisting of 8 STEPS.

Each STEP is defined by a set of 10 parameters. 

The parameters determine STEP activation delays, duration, type of humidity and temperature regu

-

lation, setpoint for regulation, activation of relay AUX1/2 and procedures for completing one STEP 

and switching to the next.

By default, regulation is disabled and the setpoints are all zero. The auxiliary relay is enabled

The climate profile START or STOP command is activated by briefly pressing the START/STOP RESET 

key (E).

The climate profile RESET command is activated by pressing and holding the START/STOP RESET key 

(E).

Example

3-STEP climate profile and temperature/humidity regulation in Neutral Zone mode. The first STEP 

starts with a delay while the others start on completion of the previous STEP. The Humidity Setpoint 

is fixed whereas the Temperature Setpoint is variable.
