Applications

4.In this application, the maximum configurations are as follows:

The maximum of CMP TOTL = 3.

The maximum of EHTG STG CNT = 3.

The maximum of CMP TOTL plus EHTG STG CNT = 4.

If these limits are exceeded, CMP TOTL will be set to 0 and EHTG STG CNT will be set to 0. These points will remain at 0 until they are set correctly. This prevents the application from trying to use the same DO as both a compressor and a stage of electric heat.
