Miller mercury thermostat to Honeywell RTH7600 thermostat
Here's the old mercury thermostat.
And here's the new digital one.
I think I've hooked it up right.
And programming the digital one, for the
0170 function, do I just select 7: heat pump with back up/ AUX heating?
Does anyone know from the pics if we have a heat/cool multiple stages?
And for 0190 do I select 0 or 1?
Thanks in advance for any help.

The connections are correct. I'm checking the programming features.
You have single stage heating and cooling with back up AUX heat.
170----- 7
180----- 1
190 stays 0
240 is cycle rate...... try 7 to start.
270 is em heat cycle rate..... same as 240
300 stays 0
