Stages describes the number of heat or cool sources that you need to control with a single thermostat.
Voltage, or volts, is a measurement of the difference between two electric fields (in heating terms, the difference between the Earth's electrical field and the electricity running through your wires).
The Tekmar 256 Boiler Control is a microprocessor-based control designed to regulate the supply water temperature from a single boiler based on the outdoor temperature. To avoid boiler short cycling and large temperature swings, the 256 is able to continuously adjust the boiler differential. The Tekmar 256 includes control functions such as Warm Weather Shut Down (WWSD) and Minimum Boiler setting. The control has a liquid crystal display (LCD) that normally displays the Boiler Supply temperature, but can display other temperatures and settings.

solves the problem with hot water boiler
from Toronto, Ontario, Canada
Hot water heating is great except in the spring and fall when not as much heat is needed. The Tekmar Boiler Control solves this problem by automatically adjusting the water temperature based on outside temperature. This product simplified a situation I have been dealing with for years on an older boiler system.
Set back on a boiler
The Tekmar boiler control works great and was easy to install. I have a Burnham power vent boiler so I needed a separate 24VAC relay to control the circulation pump.
Product & Shipping as Promised

Best way to lower heating costs in my home and still remain comfortable.

Best (simple) outdoor reset available.
By Joe S. [@]
from Rahway, NJ
This is the most practical outdoor reset available right now. It's incredibly easy to program, saves a bunch of money, and is priced right. It's always our first choice for residential and smaller commercial systems. The installation is simple. Adapts to any type of hydronic boiler. I'm a service technician and installer; I have this control in my own home, and it's the best investment I've made for my boiler so far.
This is worth your money .Istalls easy and fast set up too MUST FOR oil heating systems
