1 1-1xx Series 1-30x Series Pneumatic Room s General Instructions Application The 1-41x Series Pneumatic Room s are designed for proportional control of pneumatic devices and actuators in environmental control systems. These two-pipe thermostats incorporate a highly sensitive bimetal thermostatic element and a pilot operated relay with pneumatic feedback for accuracy and stability over the entire operating range. These thermostats have a serrated thumb wheel for setpoint adjustment. s are also available with preassembled internal dial stops. covers are available in various styles to meet particular requirements. options include models with a setpoint scale and a thermometer, a setpoint scale only, a thermometer only, or blank. An external setpoint adjustment cover is available on some models, or can be field-installed on covers where desired. Full Dial Shown (s must be ordered separately except as noted.) Features Factory-calibrated, stainless steel ball-in-seat provides pneumatic feedback for stable, linear operation. Easy-to-use throttling range adjustment and recalibration.

INSTALLATION Inspection Inspect the package for damage. If damaged, notify the appropriate carrier immediately. If undamaged, open the package and inspect the device for obvious damage. Return damaged products. Requirements Tools (not provided): Appropriate screwdriver for mounting the thermostat calibration and cover screw wrench (or 1/16 and 1/4 hex wrenches) Training: Installer must be a qualified, experienced technician Appropriate accessories Piping diagrams Location Caution: Do not locate the thermostat near sources of heat or cold, such as lamps, motors, sunlight, or concealed ducts or pipes. Doing so will affect the accuracy of the thermostat. Avoid installing the thermostat on outside walls. If such a location is necessary, mount the thermostat on an insulated back plate (accessory item). Mount thermostats only after the wall surfaces have been finished. Locate the thermostat where it will be exposed to an unrestricted circulation of air, which represents the average temperature of the controlled space. F Copyright 008 TAC All Rights Reserved. 3

6 Optional Mounting Eliminate the pipehead fitting by using the -0 thermostat conversion kit and the included instructions, plus the following: 1/4" Air Lines: Install the 1/4" barbed couplings into the air lines. Connect the tube assembly to the 3/16" end of these couplings. 1/4" Copper Air Lines: Solder the barbed couplings into the copper lines. The tube assembly can then be connected to the 3/16" end of the couplings. CALIBRATION Setpoint Adjustment Internal Setpoint Indicator Limit Stops () (Accessory) Fahrenheit Scale F 1 6 T R Scale Setpont Indicator C H 5 Pressure Tap Celsius Scale Calibration Screw Calibration and Throttling Range Setting The 1 series thermostats are factory calibrated and are shipped with the throttling range set at 3 F. They should not require calibration upon installation. However, if it is necessary, change the calibration or throttling range setting as follows: 1. Remove the thermostat cover, using a thermostat wrench (1/4 hex wrench), and install a -138 branch tap gauge adaptor into the branch pressure tap hole (Figure-10).. Measure the ambient temperature with an accurate thermometer. This temperature must be within the range of the thermostat. 3. Move the setpoint adjustment to the measured ambient temperature, using the internal setpoint indicator. 4. Taking care not to breathe on, or place the hand near the bimetal, use a thermostat wrench (1/16 hex wrench) to turn the calibration screw until the branch line pressure indicates 9 psig. Clockwise rotation increases the branch line pressure. Counterclockwise rotation lowers the branch line pressure. 5. Reinstall the thermostat cover and set the thermostat to the desired setpoint. ic Bimetal Figure-10 Calibration Features and Limit Stop Accessory. MAINTENANCE The thermostat requires no maintenance. Regular maintenance of the total system is recommended to assure sustained, optimum performance. FIELD REPAIR None. Replace an inoperative thermostat with a functional unit. DIMENSIONAL DATA 1/8 (.318) M B Internal Stop Kit (Accessory) The internal stop kit, model 0-71, consists of two screws and two nuts (Figure-10). Install this kit as follows: 1. Move the setpoint adjustment to one extreme limit.. Place a nut in the depression in the top plate and move the adjustment cam over the nut, to where the slot in the cam exposes the threads of the nut. 3. Thread a stop screw into the nut far enough to allow the stop to slide in the slot. Repeat on the other side. 4. Move the setpoint adjustment to the desired temperature, using the internal setpoint indicator. 5. Slide the stops to the desired limits and tighten both screws. 1-1/4 (3.18) 1-3/8 (3.5) -1/3 (5.16) Dimensions are in inches (mm). 1-3/8 (3.5) Figure-11 Mounting Dimensions. -1/3 (5.16) F Copyright 008 TAC All Rights Reserved. 6
