5 PCU-EC2 (Modbus) Red marked versions have never been released First released version Added Fan speed log, support for VR units added Electrical heater for VTC700 hysteresis changed to +-1 C Damper heat regulation blocked for 3 minutes after use of electrical heater so that the afterheat doesnt activate the bypass damper Date problem fixed, clock problem fixed, Defrost level 0 for VR added, fan speed log function updated Update for Westcontrols test bench. No changes in function Updates to improve stability of the cards. Should fix errors like strange icons, wrong language and units stopping or changing fanspeed Fixed fan alarm problem, both fans now stops during fan alarm, an error that probably was introduced already in Also changed frostprotection function so that the frost protection is active when the supply air drops below 5 C and the outside air is below 0 C (Only used with water heater) Communication improvment, calibrated clock frequency SAVE units Added startup wizard, VTR150/200 units, digital rotorguard for VTR units, modbus control of digital inputs and k-factor menu for "fake constant air flow". Removed 20% difference limit between EF and SF Added functionality for l/s control of non constant air flow fans, used together with system curves, also added in menus. Not tested for VR use, only for VTR/VSR. VTR system added. Startup wizard added Added VSR300/500. Some improvements for the wizard. Some values in the wizard were not stored in case the wizard was completed very fast. System curves added to modbus Added VSR150/VTR300/VTR500. Speed control added as an option to system curves, both in the wizard and in the menus. Also changed frostprotection function so that the frost protection is active when the supply air drops below 5 C and the outside air is below 0 C (Only used with water heater) Communication improvment, oscillator calibration.

6 PCU-EC3 (Modbus/Wireless/Compatibility) First released version, wireless control functions and compatibility for old systems Approved functionality for VTC200 unit New CD3 control panel created wrong supply air temperature settings for PCU-EC3. (12-16C five steps 1K/step) Regarding older unit types VR400/700DC/DCV/DE/DK. (12-22C five steps 2,5K/step) Demand control, airflow boundary settings between High and Nominal.

Some updates for VR functionallity, VR not released Added fan speed log, VR functionality, manual fan stop for VR systems Defrost level 0 for VR added, speed logging function updated Support for all new functions in Support for all new functions in Update that should fix a lot of "bluescreen" problems in the CD panels Communication improvment, oscillator calibration.

8 CD3 Panel (Modbus/Startup wizard/wireless) Unit type SAVE VTR/VSR/VTC (PCU-EC2 and PCU-EC3) Flow values in the wizard is not an optional question anymore, it has to be completed Support for new functions in wizard and models Communication improvment, calibrated clock frequency Support for new functions in wireless and compatibility for EC and EC2 print cards Improvment of compatibility with EC and EC2 print cards. Airflow adjustments improved for old unit types Approved version for production of version No changes between the versions CD Control panel 3, used as spare part for old PCU-EC (VR units without Modbus) Minor changes for language strings and change in "Fan control" menu structure.
