White rectangular thermostat with front dial and rear capillary bulb sensor

Dayton

Dayton 2NNR6 Line Volt Mechanical Thermostat 0-120°F

SKU CH-2KQG-BXJ4G

Controls heating or cooling systems with a remote sensing bulb across a 0 to 120°F range and a 3.5°F differential

  • Product typeRemote Bulb Temperature Control
  • Controls 0-120 °F range for broad heating/cooling applications
  • Remote bulb senses temperature away from the thermostat body
  • SPDT switch handles 16 A at 120 VAC and 8 A at 240 VAC
  • 5 °F differential reduces short-cycling of equipment
  • Operates on 24-600 VAC line voltage without external transformer

Line-voltage mechanical thermostat

The Dayton 2NNR6 is a line-voltage mechanical thermostat designed for heating and cooling systems that operate directly on mains voltage. It suits installers and maintenance teams who need a simple, non-programmable control with remote temperature sensing.

SPDT switch rated 24–600 VAC

The single-pole double-throw switch handles 16 A at 120 VAC and 8 A at 240 VAC, making it compatible with a wide range of line-voltage loads. A fixed 3.5-degree differential and open-on-rise action define the switching behaviour, so the control cannot be adjusted for tighter temperature bands.

Verify voltage, current and sensing needs

Before ordering, confirm that the load voltage falls between 24 and 600 VAC and that the connected equipment does not exceed the listed amp ratings. Ensure the application can accommodate a remote bulb sensor and that a non-programmable, fixed-differential device meets the control requirements.

Questions about this item

Should I pick a different temperature range or voltage rating for my application?

This model covers 0 to 120 °F and handles 24 to 600 VAC, so choose it when your process stays within those limits.

What does the 16 A rating at 120 VAC mean for the load I can switch?

It means the single SPDT switch can carry up to 16 amps on a 120 VAC circuit, or 8 amps at 240 VAC, for heating or cooling loads.

How does the line-voltage mechanical interface limit what I can connect?

The thermostat switches line voltage directly up to 600 VAC, so it controls heaters, compressors or fans without a separate low-voltage relay.
