[cryotec]

i need help from you guy's on out put voltage on the above unit . I know that the voltage between terminal 2&3 is 0-12 volts DC. What i want to know is what is the voltage on full load cooling and full load heating? Does anybody know?

It cant be as it is used for cooling and heating signel so it has to change to do that?

12volts!!! its a signal, the choice of whether heating or cooling is decided by indoor an outdoor pcbs.
