Ranco dual stage aquastat: Easy yet effective
Easy to install, easy to configure, this Ranco dual stage aquastat is the perfect controller for use with water-to-water hydronic geothermal applications. The controller has two set points for either heating or cooling. Works with 24VAC (directly from the heat pump is possible).
Off-Staging with two differential settings
Off-staging is the concept of turning heating (or cooling) stages off as the temperature gets close to its setpoint. It is an important setting because it limits the on/off cycling of the heat pump compressor. More advanced controllers, such as the ECO-0550, have this function build in automatically. However, the Ranco dual stage aquastat has not only two set points but also two differential settings. As a result, you can set up this control in such a way that the staging for your system is optimal and mimics the off-staging of other controllers.
- Two set points (heating or cooling) with individual differential settings
- Comes with integrated temperature sensor
- Requires 24VAC input (heat pump 24VAC compatible)
- Two NO/NC dry contact outputs
