SIEMENS 192-204 Pneumatic Thermostat 45-85F DA/DA

SKU CH-Y4C6-6DPK2

Pneumatic thermostat with dual DA outputs for heating and cooling, auto-reset setback and test port, 45-85°F

  • Product typeLearning Thermostats
  • Automatically resets setpoint during unoccupied hours to reduce heating and cooling costs
  • Dual-output design provides separate heating and cooling control in one unit
  • Test port allows quick output pressure checks without removing the cover
  • Replaces outdated thermostats of almost any brand for proportional pneumatic valve and damper control
  • Includes wall plate and screws for connection to various rough-in boxes

Application Scope

The Siemens 192-204 pneumatic thermostat serves commercial HVAC systems that require proportional valve and damper actuator control. It is intended for facilities managers and contractors working on large-volume heating and cooling installations with 2-pipe configurations.

Upgrade Path

This unit replaces outdated thermostats of nearly any brand when a dual-output, direct-acting device is needed for both heating and cooling sequences. The jump is worthwhile when automatic setback during unoccupied periods is required to reduce energy expenditure.

Installation Notes

A wall plate and mounting screws are included for connection to various rough-in boxes, and a test port permits output pressure verification without cover removal. The cover itself is not supplied, so installers must source it separately or reuse an existing one.

Questions about this item

What rough-in boxes does the included wall plate and screws connect to?

The supplied wall plate and screws let you connect the thermostat to a variety of standard rough-in boxes without extra adapters.

How is the thermostat installed and what step is often missed?

Mount the unit using the included wall plate and screws, then connect the pneumatic lines; the step often missed is verifying output pressure through the test port before replacing the cover.

What maintenance or replacement will this thermostat need later?

Periodically check the pneumatic tubing and connections for leaks, and recalibrate the setpoint if the dual-output control drifts over time.
