Dwyer Instruments TSW-160 Temperature Switch
The Dwyer Instruments TSW-160 is a rugged, weatherproof digital temperature switch designed for reliable HVACR control in demanding environments. This single stage temperature controller operates on a 12 to 24 Vac/Vdc power supply, making it a versatile choice for low voltage HVAC systems, commercial refrigeration, and chiller applications. Featuring a NEMA 4X (IP66) enclosure, the TSW-160 protects sensitive electronics from moisture and corrosion, which is essential for walk-in coolers and wood boiler systems. The unit utilizes a high-capacity 20A SPDT relay capable of handling up to 2HP at 240V, allowing for direct control of heavy inductive loads without additional contactors in many setups. Technicians can easily configure the device using the 3-digit LED display and front keypad, with passcode security and a physical jumper lock to prevent unauthorized setpoint adjustments. Compatibility with both PTC and NTC thermistor probes ensures flexible temperature monitoring and control across a wide operating range of -58 to 302°F.
Key Benefits- Industrial-Grade Protection: The NEMA 4X housing ensures durable operation in wash-down areas or outdoor brewery cooling environments.
- High Load Capacity: Equipped with a 20-amp SPDT output relay, eliminating the need for intermediary relays on smaller compressor and pump circuits.
- Universal Compatibility: Supports multiple thermistor sensors and features field-selectable engineering units (°F/°C) for precise thermal management.
- Tamper-Resistant Configuration: Includes a software passcode and hardware jumper to maintain HVAC system integrity once commissioned.
- Installer-Friendly Design: Features multiple conduit knockouts and fast-tab terminals for rapid wiring of line voltage to the relay common.
How do I prevent others from changing the temperature setpoints?
The Dwyer TSW-160 includes dual-layer protection. You can engage a physical jumper lock on the internal circuit board and set a software passcode (H5 parameter) to restrict 12 different programming parameters, ensuring your cooling system settings remain fixed.
Can this switch be used for both heating and cooling applications?
Yes. The control type is field-selectable between heating (Ht) and cooling (Co) modes. By utilizing the Normally Open (NO) terminals for heaters or Normally Closed (NC) for coolers, you can precisely manage industrial heating or refrigeration cycles.
What happens if the temperature probe fails?
The digital temperature switch features built-in diagnostics for shorted or open probes. You can pre-configure parameters C2 and C3 to determine exactly how the output relay should behave (on/off cycling) during a probe error to prevent equipment damage.
