III.I New Features and Problems fixed (Firmware)
====================================

Version 1.12

	- When the CO2 level is available, the minimum fresh air intake will now modulate between
	  the minimum and maximum fresh air intake setpoints proportionally with the CO2 level.
	- New option to allow the Economizer and the Mechanical cooling to function simultaneously.
	- New option to remove the low mix air temperature limit safety regarding fresh air intake.
	- A new option was added to set the reversing valve action (normaly heat or cool) which 
	  prevent the reversing valve to be ON for a long period of time.
	- The device switches to bypass state when an input configured only as Space Temperature is 
	  shorted. This input must be configured as Standard Thermistor or resistive TransTable.
	- Every user defined timers have a minimum value of five seconds.
	- The OptimumStart function has been simplified.
	- The option for fresh air damper minimum control using air volume has been removed.

Version 1.03

	- The apb is now compatible with the new plastic enclosure controller.
	- Bug fix: In some cases, the optimum start can leave the occupancy state in 
	  unoccupied mode during occupied or standby modes until the occupancy state is 
	  changed. Fixed.
	- Bug fix: When the REVERSING_VALVE is configured and the change over time is null, 
	  if the unit switches from cooling to heating, the reversing valve will stay OFF and 
	  the cooling will stay ON while there is a heating demand. Fixed.
	- Adjusted type 2 and 3 thermistor range (-40 to 150°C).

Version 1.02

	- Bug fix: When the REVERSING_VALVE is configured and the change over time is lower
	  than the cooling stage min ON time, the unit could switch from heating to cooling
	  without turning the reversing valve OFF thus staying always ON and heating while 
	  there is a cooling demand. Fixed.
	- Bug fix: After an optimum start has taken effect and the occupancy state is set to 
	  occupied, the unit status will display the morning warmup mode until a heating or 
	  cooling demand takes place. This bug has no internal effects. Fixed.
	- The first cooling stage will wait until the demand has reached 51% instead of75% 
	  after switching from the economizer to the mechanical cooling.

Version 1.01

	- Hardware outputs (analog) can now be configured as 2V to 10V.
