24V Low Voltage Thermostats for HVAC Heating and Cooling

Toupwell supplies 24V thermostats for compatible furnaces, air conditioners and heat pump systems. Our range includes single-stage, multi-stage, programmable, non-programmable and WiFi options for residential and light commercial projects.

Select a low voltage thermostat according to the equipment type, heating and cooling stages, power supply and wiring requirements. We support HVAC distributors, installers and private-label brands with model selection, sample evaluation and OEM/ODM development.

Our Thermostats Wholesale range brings together controls for different heating and cooling applications, helping procurement teams source products matched to their markets.

Find the Right 24V Thermostat Configuration

Single-Stage Heating and Cooling

Our single-stage thermostats serve applications requiring a single stage of heating and cooling, subject to the selected model’s configuration.

The range includes TP815 and TP815-P, providing non-programmable and programmable choices. TP808S is another option for compatible single-stage systems. Confirm the equipment type and terminal functions before choosing a replacement.

Multi-Stage HVAC Control

Systems with additional heating or cooling stages need a thermostat with the corresponding outputs and operating logic. Our multi-stage thermostats include TP825-series and TP808-series options.

Stage capacity must be checked separately for conventional and heat pump operation. The number of heating stages may include auxiliary heat, depending on the model and system configuration.

Heat Pump Applications

Selected heat pump thermostats support reversing-valve control and configurations for auxiliary or emergency heating.

Specify compressor stages, O/B operation and backup heating requirements when requesting a recommendation. Heat pump compatibility does not automatically establish compatibility with every dual-fuel arrangement.

WiFi and Programmable Options

The TP808W provides app-based control through Tuya Smart or Smart Life, with supported Alexa and Google Assistant functions.

Our WiFi thermostat range includes connected controls for compatible 24V HVAC equipment. Confirm the exact model, power requirements and network conditions during sample evaluation.

Compare Representative Thermostat Models

Confirm the final model specification before ordering. Functions available across a series are not necessarily included in every version.

Technical Reference: TP808W WiFi Thermostat

The following parameters apply to the TP808W reference model rather than the complete low voltage thermostat range.

Stage capacity, auxiliary heat and terminal assignments must be verified against the selected operating mode and wiring diagram.

Check System Compatibility Before Replacement

Conventional and Heat Pump Systems

A conventional furnace and air conditioner use a different control sequence from a heat pump. Select the correct equipment type and supported stage configuration during commissioning.

A 24V rating identifies the supply category; it does not establish complete compatibility with the equipment.

C-Wire and Power Requirements

The C-wire provides the common connection for a continuous 24VAC supply. Requirements depend on the thermostat’s power design and installation.

Confirm whether the chosen model needs an R/C supply, supports battery operation or can use an approved accessory. Battery capability on one model does not mean it is available on another.

Terminal Functions and Existing Wiring

Before replacing a thermostat, compare terminal labels and functions with both the equipment and new thermostat diagrams. Wire colour alone is not a reliable guide.

● Identify conventional or heat pump equipment.

● Confirm heating, cooling and auxiliary stages.

● Check supply voltage and C-wire availability.

● Verify fan and reversing-valve requirements.

● Review single-transformer or dual-transformer wiring.

● Confirm installation dimensions and mounting conditions.

These products are intended for compatible low-voltage control circuits. Direct switching of line-voltage heating loads requires a different control arrangement.

Controls for Homes, Apartments and Light Commercial Projects

Residential Replacement

Choose a model that matches existing equipment and wiring. Clear displays, Fahrenheit/Celsius options and accessible controls help occupants manage daily temperature settings.

Apartments and Rental Properties

Non-programmable models provide straightforward operation, while programmable versions allow schedules to follow typical occupancy. Connected versions add remote access where the installation supports it.

HVAC Distribution and Private-Label Supply

A coordinated range of single-stage, multi-stage and WiFi products helps distributors serve different installation requirements. Toupwell supports product matching and branding discussions before sample approval.

Our North American HVAC control solutions provide another route to evaluating equipment and thermostat combinations.

Manufacturing and OEM/ODM Support from Toupwell

Toupwell brings over 17 years of thermostat industry experience to standard product supply and customized development.

● Production processes include SMT, AOI inspection, DIP assembly and functional testing.

● Products undergo 24 or 48 hours of aging testing according to their requirements.

● Private-label options include logos, housing colours, packaging and localized manuals.

● Development support can cover software, hardware, interface and structural changes.

● Two-year after-sales support is available under the agreed supply terms.

Our OEM/ODM thermostat services help brands define functions, evaluate samples and prepare products for their markets.

Applicable compliance documents should be confirmed for the exact model, radio configuration and destination. Sample schedules and production lead times depend on the order scope.

Frequently Asked Questions

Q1: What does a 24V thermostat control?

It sends control signals to compatible HVAC equipment. It does not directly supply operating power to a furnace, compressor or other major load.

Q2: Is a 24V thermostat suitable for every heating system?

No. Voltage, terminal functions, system type and stage capacity must all match. Proprietary communicating equipment requires additional compatibility review.

Q3: What do 1H/1C and 3H/2C mean?

They describe heating and cooling stage capacity. The applicable capacity can differ between conventional and heat pump operation, so check the model’s system-specific wiring.

Q4: Does every low voltage thermostat require a C-wire?

Requirements vary. Confirm the selected thermostat’s continuous-power or battery arrangement rather than assuming it works without a common wire.

Q5: Can one thermostat support both conventional and heat pump systems?

Selected models support both, with different installer settings and wiring. Confirm reversing-valve and auxiliary heating requirements for heat pump applications.

Q6: Can Toupwell supply our own branded thermostat?

Yes. Branding and packaging options are available, along with evaluated software, hardware and structural customization. Minimum quantities and development schedules depend on the changes required.
