Product Description
Mechanical Pressure Supervision
The Honeywell FEMA DWR06 is a mechanical pressure monitor for supervising maximum and minimum pressures. The DWR series is calibrated for rising pressure: the value selected on the scale corresponds to the switching point as pressure rises, while the reset point is lower by the switching differential.
Honeywell identifies DWR monitors for fuel gases covered by DVGW Worksheet G 260, liquid fuels such as fuel oil, steam systems and hot-water systems within the standards stated in the official product documentation. The rugged switching enclosure uses seawater-resistant die-cast aluminium.
DWR06 is the standard fixed-differential configuration. Adjustable differential belongs to the separate DWR06-203 configuration and must not be assumed for the base DWR06.

Installation Essentials
Verify Before Commissioning
- Disconnect electrical power before wiring or adjustment.
- Use a pressure gauge for precise switching-point adjustment; the scale provides an approximate value.
- Fasten only at the hexagon nearest the pressure connection—never use the housing or plug as a lever.
- For gas applications, the internal thread is permitted only up to 4 bar; use a flat sealing ring above 4 bar.
- Prevent condensation in the sensor and switching device below 0 °C.
- Installation and safety validation must be completed by qualified personnel under applicable local standards.
Lifecycle & Replacement
Discontinued Product — No Published Direct Successor
Official lifecycle statement: Honeywell marks the DWR Pressure Monitor series as discontinued. Honeywell's public product page does not state the discontinuation date, last-time-buy date or product-support end date. No Honeywell document reviewed for this page identifies a direct, one-for-one DWR06 successor.
Is another model a complete replacement?
No model should be described as a complete replacement without application-level verification. Similar pressure range alone is insufficient.
- 0.1–0.6 bar switching range and required reset point
- Fixed or adjustable switching differential
- Maximum permissible pressure and process medium
- G 1/2 A / G 1/4 pressure connection and sealing method
- SPDT contact logic, electrical load and wiring
- IP rating, ambient temperature and mounting position
- TÜV/DVGW or application-specific approvals
- Installed dimensions and safety-circuit validation
Related DWR06 configurations
These Honeywell configurations have different functions and are not automatically interchangeable with standard DWR06:
DWR06-203: adjustable switching differential.
DWR06-205: maximum-pressure limiter with mechanical interlock/reset.
DWR06-206: minimum-pressure limiter with mechanical interlock/reset.
DWR06-213: gold-plated contacts for defined low-voltage loads.
DWR06-205: maximum-pressure limiter with mechanical interlock/reset.
DWR06-206: minimum-pressure limiter with mechanical interlock/reset.
DWR06-213: gold-plated contacts for defined low-voltage loads.
A change to an electronic switch or another DWR configuration can require wiring, power supply, mechanical connection, programming, approvals and safety documentation changes. Treat it as an engineered migration, not a drop-in swap.

Frequently Asked Questions
What is the pressure range of Honeywell FEMA DWR06?
DWR06 has an adjustable pressure range of 0.1 to 0.6 bar, a switching differential of 10 to 50 mbar and a maximum permissible pressure of 6 bar.
How does Honeywell FEMA DWR06 switch as pressure rises?
The scale is calibrated for rising pressure. At rising pressure, contact 3–1 opens and contact 3–2 closes. The reset point is lower than the switching point by the switching differential.
When was Honeywell FEMA DWR06 discontinued?
Honeywell marks the DWR Pressure Monitor series as discontinued, but the public product page does not provide a discontinuation date, last-time-buy date or support end date.
Which model directly replaces Honeywell FEMA DWR06?
Honeywell does not identify a direct one-for-one successor in the public official documents reviewed for this page. DWR06-203, -205, -206 and -213 are functionally different configurations, not automatic replacements.
What information is needed to evaluate a DWR06 replacement?
Provide the full nameplate, application medium, switching and reset pressures, electrical load, wiring, pressure connection, mounting arrangement, required approvals and clear installation photos. A qualified engineer should validate any safety-related change.

Buyer Guide
What Buyers Should Confirm Before Ordering DWR06
For a discontinued pressure monitor, matching the model name alone is not enough. Confirm the installed function and configuration before purchasing to reduce incorrect orders, installation delays and safety-review issues.
Check the Full Nameplate
Send a clear photo showing DWR06 and every suffix or marking. DWR06-203, DWR06-205, DWR06-206 and DWR06-213 have different operating or contact characteristics.
Confirm Pressure & Medium
State the normal pressure, required switching point, reset point, process medium and maximum system pressure. The base DWR06 range is 0.1–0.6 bar.
Match Mechanical & Electrical Details
Verify the G 1/2 A or G 1/4 pressure connection, sealing arrangement, SPDT contact logic, electrical load, wiring and available installation space.
