Danfoss 013G-2922 Remote Sensor

The Danfoss 013G-2922 Remote Sensor is a high-performance thermostatic radiator valve (TRV) operator designed for professional hydronic and low-pressure steam heating systems. This tamper-resistant unit is specifically engineered for the RA 2000 series, featuring a valve-mounted dial integrated with a 6-foot (2m) capillary remote sensor. By divorcing the sensing element from the valve body, this component ensures precise ambient temperature regulation even when the radiator is obstructed by cabinetry, curtains, or architectural enclosures that would otherwise cause "heat stacking" and false readings. The gas-filled technology within the sensor facilitates a rapid response to load changes, maintaining a narrow P-band for superior energy efficiency. Contractors should utilize the set-screw mount for a secure, vandal-proof installation in public or high-traffic commercial spaces. This operator is compatible with the Danfoss RA 2000 valve body, allowing for field-replaceable packing glands without system shutdown.

• Precision Sensing: The 6-foot capillary remote sensor ensures accurate room temperature control by monitoring air away from the heat source.
• Tamper-Resistant Design: High-durability construction with a locking set-screw prevents unauthorized set-point adjustments in commercial environments.
• Fast Reaction Time: Gas-filled bellows provide quicker actuation than standard liquid-filled sensors, reducing temperature overshoot.
• System Versatility: Fully compatible with Danfoss RA 2000 valves for use in both hot water and two-pipe steam applications.
• Frost Protection: Includes an integrated frost setting to prevent coil freeze-up during unoccupied hours.

Can the 013G-2922 be installed vertically?

While the dial is valve-mounted, the remote sensor should be mounted on a wall or skirting board where air circulates freely. If the valve itself must be vertical, the remote sensor compensates for the convective heat that would typically disrupt a built-in sensor.

What is the temperature range for this operator?

This model typically regulates within a range of 45°F to 86°F (7°C to 26°C), providing ample overhead for most commercial and residential heating requirements.

Is this compatible with non-Danfoss valves?

The 013G-2922 is designed for the RA 2000 platform. For installation on older RAV or RAVL bodies, specific Danfoss adapters are required to ensure proper stroke and shut-off pressure.
