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 “+” and “-“ buttons to select the programme number (Factory default is P9)
Press “PROG”. The programme number will stop flashing and the first block on 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 “BYPASS”.
