Gray rectangular thermostat with dial and remote sensing bulb

Emerson Climate Technologies

Emerson Climate Technologies 16 87 009S1 line voltage mechanical thermostat hvac control

SKU CH-WN64-BYFPC

Line-voltage mechanical thermostat switches heating or cooling from −30 °F to 90 °F with a 4.5 °F to 40 °F differential at 120–240 VAC and 15 A full-load

  • ColorGray
  • Wide -30 °F to 90 °F control range covers extreme environments
  • 15 A at 120 VAC handles heavy line-voltage loads directly
  • Adjustable 4.5 °F to 40 °F differential lets you tune cycle timing
  • SPDT switch action opens or closes on temperature rise for flexible wiring
  • Remote sensing bulb included enables temperature measurement away from the thermostat body

Line voltage mechanical thermostat

The White-Rodgers 16 87 009S1 is a line voltage mechanical thermostat built for HVAC systems that require direct 120 to 240 VAC switching. It suits installers and facility managers who need a simple heat or cool controller without programming complexity.

SPDT switch with remote sensing bulb

A single SPDT switch rated at 15 A at 120 VAC opens or closes on temperature rise, and the included remote sensing bulb allows the sensing point to sit away from the thermostat body. The gray enclosure measures 5-3/8 inches high by 2-5/16 inches wide for standard mounting.

Control range -30 to 90 degrees F

The adjustable range spans -30 to 90 degrees F with a differential of 4.5 to 40 degrees F, so the installer can set both the target temperature and the swing that fits the application. Buyers who need programmable schedules or digital precision should look elsewhere.

Questions about this item

What voltage range does the 120 to 240VAC line-voltage thermostat support in practice?

The thermostat operates on 120 to 240VAC and carries a 15A full-load rating at 120VAC, so the circuit breaker and wiring must be sized for that current.

What are the exact mounting dimensions for the 5-3/8 In. height and 2-5/16 In. width?

The unit measures 5-3/8 inches tall by 2-5/16 inches wide; verify the electrical box or surface opening matches these dimensions before mounting.

How is the remote sensing bulb installed and which step is commonly missed?

The remote sensing bulb is included and must be placed in the controlled space; the step often missed is securing the capillary tube without kinks so temperature changes reach the SPDT switch correctly.
