Honeywell 288117 Direct wired wall module without temperature dial - -US/U TR21-c1

20 K ohm NTC non-linear Temperature Wall Module w/

The Honeywell 288117 Direct wired wall module is a linear 20 kOhm ceramic wall thermostat. This Honeywell 288117 direct wired wall module has an NTC (negative temperature coefficient) and prevents overheating using an internal negative feedback heating element to keep your room at a desired temperature.

This Honeywell direct wired NTC wall modules is the part of a Honeywell thermostat system. This non-linear NTC thermistor is made of PTC (positive temperature coefficient) material which designed for use in residential applications with single-stage or two-stage electrical heaters and heat pumps, which have the internal electronic control devices for temperature setting, time clock sequences and energizing the heaters, fans, etc.

The Honeywell US/U TR21-c1 temperature wall module is a direct wired, 1-pole non-linear, NTC thick film resistor and is the main component of a Building Management System. This module contains all of the functionality of the R81006 series with a non-volatile memory that stores set points and other user data. It also has a 24-hour clock to provide programming dates and times and may be displayed in either 12 hour or 24 hour format.

The Honeywell TRW21 is a 28VAC dual input direct-wired wall module without temperature dial. This module is used to provide heat. It has a NTC sensor and internal circuit board. It can be purchased with or without a temperature control dial. This module is compact and lightweight for easy installation.

The Honeywell 288117 Direct wired wall module without temperature dial is a rectangular thermister designed to measure room temperature for commercial applications. This module will directly plug into a Honeywell 5800 series process control panel.

This black wall module is designed to be installed in an indoor environment. It is suitable for use with the Honeywell Digital Thermostat T87C/M87C or Honeywell Programmable Thermostat (800 series). The temperature sensor will transfer the inside temperature information to the thermostat which will then be used to adjust the system accordingly.

This wired wall module is designed to interface with Honeywell and compatible security controllers through the Honeywell HT3110 transmitter outputs. The module provides tamper, burglary, fire, heat and smoke shut-off outputs.
