Honeywell R845A Q & A

How does the r845a work?

• The R845A may be directly controlled by any 2-wire series 80 thermostat. Switching relay with internal transformer, provides Dpst switching for hot water zone control systems, or spst control of two separate loads. Provide intermediate switching of a line voltage device form a low voltage controller.

What is Honeywell r452a?

• Honeywell R452A DESCRIPTION R452A was developed by Honeywell and Chemours as a lower GWP R404A replacement in transport refrigeration with some use in DX low to medium temperature refrigeration, you may also see it referred to by their respective manufacturer trade names - Solstice® 452 and OpteonTMXP44.

Is the r845a1030 UL & CSA listed?

• This item is unavailable online and in stores. The R845A1030 Switching Relay with Internal Transformer is UL and CSA listed. It provides DPST switching for hydronic zone-controlled heating systems or SPST control of 2 separate loads.

How does the rt8845a control dynamic output voltage control?

• The RT8845A features a PWM VID input for dynamic output voltage control as shown in Figure 7, which reduces the number of device pin and enables a wide dynamic voltage range. The output voltage is determined by the applied voltage on the REFIN pin. The PWM duty cycle determines the variable output voltage at REFIN.
