What temperature should my aquastat be set at?
In most cases, the high-limit temperature setting on an aquastat should be between 180 and 200 degrees Fahrenheit. If the aquastat is set at 200 degrees Fahrenheit as the high-limit setting and the pressure valve begins to leak, set the temperature back to 195 degrees Fahrenheit.
How do I adjust my Honeywell digital aquastat?

What is ZC and ZR terminals?
When an aquastat has the ZC and ZR terminals, the ZC is connected to the low temperature switch of the aquastat and to the ZC terminal of the Taco control. The ZR is a 120 Volt supply to the burner circuit to fire the boiler, but this goes through the high limit switch to control the boiler water temperature.
What should my Hydrostat be set at?
For proper operation, the low temperature limit setting should be at least 10° below the high limit setting. NOTE: For cold start operation, the low limit must be turned OFF. IMPOR- TANT: If low limit temperature cannot be set above 140°F, remove jumper . (Setting range: OFF or 110°-200°F).
What temperature should a residential boiler be set at?
The average setting for a gas-powered hot water boiler is 180°F. This provides the appropriate level needed for most cold weather temperatures. If you can raise the temperature manually, do not set it any higher than 210°F (which is often the limit), and try to remain down at 190°F if you need the extra heat.
What does cold start boiler mean?
Cold-start unit: This is any heating appliance that does not maintain temperature, but does produce domestic hot water. The concept allows the boiler to remain cleaner throughout the operating year and actually accelerates recovery during extended periods of domestic hot water draw.

What does a hydrostat do?
The Hydrostat sensor checks to determine if a standard well is used by looking for low resistance to ground, a condition that can only exist with a standard well. If you are installing on a standard well and either Low Water LED’s are on, setting b will not be available.
How hot does a steam radiator get?
