Pack quantity and application
This pack contains twelve non-programmable thermostats designed for residential heating and cooling systems. Each unit controls a single-stage heating and a single-stage cooling circuit. The mechanical push-button interface provides direct manual adjustment without menus or scheduling. Wall mounting hardware is included for standard installations.
Installers and homeowners seeking basic control
These thermostats suit property managers, landlords, or homeowners who want reliable temperature regulation without programming complexity. The backlit display and Fahrenheit or Celsius selection aid readability. Buyers needing weekly schedules, Wi-Fi connectivity, multi-stage equipment control, or smart-home integration should consider programmable or connected models instead.
Single-stage heating and cooling compatibility
Each thermostat operates on 120 or 240 volt supply with a 24 volt relay contact for conventional gas, oil, or electric furnaces and air-conditioning units. The adjustable temperature swing offers nine steps for cycle-rate tuning. Verify that the existing system uses a single heat and single cool configuration before installation.

Questions about this item
Does the PSD111B need a 24 V low-voltage HVAC system to operate?
Yes, the relay contact is rated at 24 V, so the thermostat requires a compatible low-voltage heating and cooling system.
Can I keep my existing 120 V or 240 V line-voltage wiring with these thermostats?
No, the PSD111B is designed for 24 V low-voltage control circuits and will not work directly with line-voltage wiring.
How do I confirm the PSD111B is controlling temperature correctly after installation?
Set a target temperature, wait for the system to cycle, then verify the room reaches that setpoint and the display shows the chosen Fahrenheit or Celsius reading.
