Hi All,
I'm integrating my first mini-split system (mitsubishi) with the Cool Automation setup with the v2.1 modules.
Unlike the Crestron stats, the CA modules do not have a Mode_OFF commands. I have discussed with their tech people and they said to use the Power_OFF for Mode OFF, which makes sense for this kind of unit.
This begs the question - does selecting an operating mode (Cool, Heat, etc) automatically turn the system on and select the mode? or do I have to send it the ON command and then the Mode command?

TIA!!

I have used the Coolpoint many times on Daikin and Mitsubishi splits and VRV. It works perfectly. As with the normal AC system remote, the Power_OFF and Power_ON are the unit Off/On in its same state. Mode changes H/C/F? and SP adjust Set Point. Only word of caution is don't display Room Temp to the user, unless you have a separate wall mounted sensor in a good place, otherwise it measures the temp in the return plenum by the fan coil, and this is wildly different from the RT. My usual TP layout is a simple ON/OFF, SP with UP/DN and MODE. Sometimes louvre control if appropriate.

Thanks!

My Question though is: does sending a Mode Command when the unit is OFF, turn the unit ON? or do you have to send the Power ON first and then the Mode command?
TIA

I've done a couple of systems with CoolMaster, and send the Power On command before every Mode command. However, I can't say if that's actually required.

The first one was replacing a Mitsubishi G50 controller, and already had the logic for Power On, so I just left it in place. Both jobs were remote, and I never tested to see if Power On was really necessary.

Sending a mode command when the unit is OFF does not turn the unit on, but it does change the mode. Its a good old system that only does what it is told to do, and doesn't guess.

Nice!! Thanks Tony and David!!
