### I have a very old floor funace. Peobably around 45 years old. There's know fan, just induction gas heat chambers with a grate on top. The unit stopped working when the HVAC guy changed the Thermostat...

He needs to put the old stat back on...... The old stat is a Millvolt stat and the new Digital ones won't work. And I don't know if they make a digital for Millvolt.... The old floor furnaces used a power pile like a oversize thermocouple for the power to operate the gas valve.

### CASIO fx-115ES I need to calculate and fnd a modulus remainder.I need to divide the number 352 by the number 91 and find the remainder. I need to use the modulus operator. Can this calculator perform...

Actually, the answer is 79.

The fx-115ES does not have a key for the modulus operation. Nor does it have an integer-part or fractional-part operation. However, it is possible to calculate the remainder using integer arithmetic.

Press MODE 4 to shift into integer mode. Then type in 3 5 2 - 9 1 * ( 3 5 2 / 9 1 ) = and see the answer 79. It's a pain as both numbers have to be entered twice, but it does get the job done.

To get back to working with real numbers again, press MODE 1 ( or MODE 2 for complex).

• Hi, This is a good stat and I have used it alot in the past as it is a older model. If you have 24 volt control voltage at the stat, and the battires are good, then you have a malfuntion in the ciruitry and will need to replace it. I have sent you a ton of manuals on there products I thiught they may be helpful. Please dont forget to rate this post as I know you will be kind. I hope I have been of help to you.
