Enclosures are offered in a White “-R2” or Beige “-R” color and are designed to be mounted over a single gang junction box or hole in the wall with the use of drywall anchors. Screw terminal blocks are available for making all connections to the temperature sensor, Set Point, “After Hours” Override, and Communication Jacks for easy access to your building management system (network). An optional 3.175 mm (1/8 in) Black foam pad with pressure sensitive adhesive are available to insulate the sensor from thermal drafts from within the wall or wall surface. The enclosure covers are secured using a 1/16 in Hex driver to secure the cover from being easily removed. An optional company logo is available for an additional charge and must be ordered as a separate line item underneath the Thermistor Room Series model number. ## **Applications** Space Temperature Sensing, Decorative Wall Applications, Office Buildings, Schools, Colleges, Commercial Buildings, OEM Opportunities ## **Warranty** The ACI High Accuracy Thermistor Room Series is covered by ACI's Five (5) Year Limited Warranty. The warranty can be found in the front of ACI's Sensors & Transmitters catalog, as well as on ACI’s website, workaci.com. ## **Specifications** ## **Sensor Type:** Thermistor **Sensor Curve:** Non-Linear, NTC (Negative Temperature Coefficient) **Number Temperature Sensing Points:** One **Sensor Output at 25 ºC (77 ºF)** **A/0.1AN Series (Type III):** 10 k Ω nominal **A/0.1CP Series (Type II):** 10 k Ω nominal **Accuracy 0 ºC to 70 ºC (32 ºF to 158 ºF)[1] :** ±0.1 ºC (±0.18 ºF) **Interchangeability 0 ºC to 70 ºC (32 ºF to 158 ºF)[1] :** ±0.1 ºC (±0.18 ºF) **Stability (5 Years)[2]** **A/0.1AN Series:** ±0.12 ºC (0.216 ºF) from 1.5 ºC to 50 ºC (35 ºF to 122 ºF) **A/0.1CP Series:** ±0.06 ºC (0.108 ºF) from 1.5 ºC to 50 ºC (35 ºF to 122 ºF) **Response Time (63 % Step Change):** 10 seconds nominal **Power Dissipation Constant:** 2 mW / ºC **Set Point Specifications / Set Point Indication:** See Ordering Grid options on this product data sheet ## **R** **Operating Temperature Range[2] :** 1.5 ºC to 50 ºC (35 ºF to 122 ºF) **Storage Temperature Range[1] :** 1.5 ºC to 50 ºC (35 ºF to 122 ºF) **Operating Humidity Range:** 10 % to 95% RH, noncondensing **Connections:** Screw Terminal Blocks (Non-Polarity Sensitive) **Wire Size:** 1.31 mm[2] (16 AWG) to 0.129 mm[2] (26 AWG) **Terminal Block Torque Rating:** 0.5 Nm (Minimum); 0.6 Nm (Maximum) **Enclosure Material | Color:** **“-R2” Enclosure:** ABS; White - **“-R” Enclosure:** ABS; Beige ## **Enclosure Flammability Rating:** UL94-HB **Product Dimensions:** See dimension drawing on this product data sheet **Product Weight:** **A/XXXX-R/RS/RO Series:** 63.5 g (0.14 lb) **A/XXXX-RSO Series:** 81.6 g (0.18 lb) - **A/XXXX-R2/R2S/R2O Series:** 72.6 g (0.16 lb) **A/XXXX-R2SO Series:** 90.7 g (0.20 lb) **Agency Approvals:** CE, UKCA, RoHS2, WEEE **Note[1] :** For best accuracy and long-term stability the sensor should be used in applications where the operating temperatures remain within the specified temperature range of 0 ºC to 70 ºC (32 ºF to 158 ºF) **Note[2] :** The sensors will operate over an extended operating temperature range of -40 ºC to 150 ºC (-40 ºF to 302 ºF) without damaging the sensors but the accuracy and long-term stability will not meet the specifications above | Contact ACI for more information **Set Point Tolerance:** ±10 % of the range **Override Option:** Short Thermistor (Default); Field (Jumper) Selectable “Dry Contact” Closure (Separate Input); Short Set Point available upon request **NIST Certification:** 3 Point NIST Certificate (not available with Setpoint or Comm Jack options) **==> picture [95 x 35] intentionally omitted <==** ## **Dimensions** **==> picture [203 x 94] intentionally omitted <==** **Front View** **==> picture [123 x 86] intentionally omitted <==** **Right View** **==> picture [154 x 83] intentionally omitted <==** **Top View** ## Standard Ordering |**Model #**|**Item #**|**Description**| |---|---|---| |**A/0.1AN-R2**|146782|High Accuracy 10,000 ohm Thermistor (Type III), Room (R2)| |**A/0.1AN-R**|146793|High Accuracy 10,000 ohm Thermistor (Type III), Room (R)| |**A/0.1CP-R2**|137079|High Accuracy 10,000 ohm Thermistor (Type II), Room (R2)| |**A/0.1CP-R**|127176|High Accuracy 10,000 ohm Thermistor (Type II), Room (R)| ## Accessories Ordering |**Model #**|**Item #**|**Description**| |---|---|---| |**A/MOUNTING PLATE BEIGE R**|106821|Wall MountingBack Plate, Plastic, Beige (”R“)| |**A/MOUNTING PLATE WHITE R2**|143369|Wall MountingBack Plate, Plastic, White (”R2”)| |**LOCKING COVER**|107370|Clear Thermostat Guard, LockingCover, Low Profle| |**A/ROOM-FOAM-PAD**|125690|3.175 mm (1/8 in)Foam Insulation Pad with Adhesive, 76.2 mm (3 in) x
