2.2.7  The unit can be installed onto a solid base without the need to mechanically fix it down.  A 

platform may need to be built up below the unit to ensure space for fitting a condensate 

drain and allowing substantial fall in the pipework.

From the home screen, press “

HUM

” to move to the humidity (% RH) activated boost 

setting (Factory default 60% RH – recommended)  

 

Use the “

+

” or “

-

“ buttons to set the humidity switching level in steps of 1% RH (range 30- 

85%RH) 

 

 

 

Press “

SET

” to record or “

The pre-programmed Thermal bypass programmes are shown in the diagram on page 18 

 

Note: Each square has a time value of 30 minutes. Black squares indicate a time period 

where the unit is in automatic bypass mode i.e. the unit will monitor the temperatures and 

open or close the bypass accordingly.  White squares (blank spaces) indicate a time block 

where the heat exchanger bypass will be permanently set to operate and divert air around 

the heat exchanger regardless of the measured and set temperatures. 

 

Each of the programmes can be 

edited

 to create bespoke programmes as follows: 

 

From the home screen, press “

PROG

” 

 

Use the “

timeline at the bottom of the screen will begin to flash. 

 

Select the day to be edited by pressing “

” until the correct day is displayed along the 

top of the screen (1 – Monday, 2 – Tuesday etc.) 

 

To add a 30 minute temperature controlled bypass block (a black square) to the timeline, 

ensure that the word “

BYPASS

” is displayed on the screen by pressing “
