With the crc100 control, do you also need ODR?

    I believe the CRC200 can work with outdoor sensor but not the 100?

    No, it uses the indoor temp only. It raises or lowers the water temp based on the temp difference between the room setpoint and the actual room temperature. It is a constant circulation control. With the CRC 200, it uses the outdoor sensor ONLY for warm weather shut down. That feature isn't in the CRC 100.

    Thanks! I was thinking that's the case but I couldn't find any difinitive information.

    Indoor reset rocks on a single zone system. It's better than outdoor reset in that application.
