Question temporary hotwater fix

I have a slant fin boiler for baseboard heat and hot water. My smart III indirect water heater tank thermostat has quit and I've ordered a new one - it won't be in for 3 days.

Would it be possible to temporarily bypass the thermostat to call for hot water - so the family can shower etc.?

First, how did you diagnose the defective thermostat ? In other words, you are _certain_ that the thermostat is bad ?

How is the thermostat wired into the boiler controls ?

If you "by-pass" the thermostat you will constantly be asking the boiler to create domestic hot water,there will be nothing to stop the demand,you will be making 180* or more hot water.....and if you are set up for priority domestic, your boiler will never switch over to heating mode.......by-passing any safety limit is almost never a good idea
