Overview

HydroStat(R) can be used in two ways. By installing the control on an exsisting immersion well, HydroStat(R) can be used as a universal replacement for common Aquastat(R) models. Whether it's a cold start or a tankless coil boiler, HydroStat(R) will provide all the temperature functions of the control being replaced.

Or, install HydroStat(R) on a Hydrolevel Electro-Well(TM) (sold separately) to automatically activate the low water cut-off function. With HydroStat(R) you can add low water cut-off protection to new or existing installations without the added time and cost to install a separate control.

Features

Dial-Type Settings

Allows for quick and easy limit and differential settings.

Dynamic Temperature Display

This 3-digit LED display continually indicates boiler temperature. Whenever the high limit, low limit, or differential temperature dials are turned, the LED instally changes to display the setting temperature. For a quick reference, the LED will scroll through the current temperature and differential setting each time the HydroStat(R) control is powered up.

Easy to Wire

HydroStat(R) uses the same terminal designations as common Aquastat(R) models. This makes field replacement fast and easy.

Four On-Board Diagnostic Indicating Lights

• Green TEMP ACTIVE - Indicates HydroStat(R) is powered and the temperature function is active
• Yellow TEMP HIGH TEMP - Illuminates any time the boiler is off on high temperature limit
• Green LWCO ACTIVE - Only illuminates when the HydroStat(R) is providing Low Water Cut-Off functionality. This function is activated by installing the control on a Hydrolevel Electro-Well(TM). This LED will not illuminate when installed on a standard immersion well
• Red LWCO LOW WATER - Indicates a low water condition in the boiler
