CU20: Replacing A CU20 With A New Power Pack (MP20 or PP20)

When replacing a CU20 with a new power pack (PP20 or MP20) you must also replaced the sensors in the system.  The time delay was built into the CU20, but it is now building into the sensors.

If you are only replacing an old sensor (wv-1600, cm-600, cm-300, etc) you only need replace the sensor and turn the time delay to 30 seconds since the old power supply still has its time delay working.
