I am using an X4 and a XP8 to control a 40 gallon planted tank and want to add a battery backup in case of power failure. When in power failure mode I want to run the return pump and heater only as a way of extending the backup time. Is there a way, without using a second heater, to lower the temp six degrees during the power failure?

Not sure why you would want to run a heater during a power failure. The only thing that runs on mine is the flow pumps which are both MP10's. My tank survived rolling blackouts a little over two years ago like this. The power was on and then off for the same amount of time. The longest was 4 hours on and 4 hours off. This went on for a week. It was below 32 degrees outside the whole week of the blackouts. It got below 50 degrees at times in the house. The tank is a 42 gallon tank. It got to just below 70 degrees. It took two day after the blackouts stopped to get back up to 76 where the heaters are set. I did not loose any tank inhabitants to the blackouts.
 
You are probably right, just trying to think of everything. I live in Michigan and we have short outages from time to time but we also get those that last days. Several years back I lost a tank of discus to an ice storm induced outage. Thanks for the reality check.
 
Sounds like you might need a generator for those times when there is a extended outage so you can use heaters. Heaters will drain a battery powered inverter quickly.
 
Heater will chew up your battery backup very quickly! That may well require a generator to run for an extended time.

Check out this thread for a DIY battery backup solution that would work with your X4 0-10v inputs.

 
Saw that Thom and that's how I plan on triggering the "backup mode". I have a generator but when I lost my discus, I was out of town, couldn't fly in because of the power outage. Swell!
