Applications and Features Fig. 1. Dimensions in inches (mm). INSTALLATION When Installing this Product… 1.Read these instructions carefully. Failure to fol- low them could damage the product or cause a hazardous condition. 2.Check the ratings given in the instructions and on the product to make sure the product is suit- able for your application. 3.Installer must be a trained and experienced ser- vice technician. WARNING Risk of electrical shock. Can cause severe injury, property damage or death. Disconnect power supply before installation and before servicing. IMPORTANT The thermostats are line voltage powered devices. All wiring must comply with national and local electrical codes, ordinances and regulations. Provide disconnect means and overload protection, as required. The TB8575A1000 thermostat must be powered by an approved 24 Vac, Class 2, NEMA rated trans- former (such as a W6380 relay control center). Location The thermostats are the temperature control element in a fan coil or air-conditioning system. They must be located about 1.5m (5ft.) above the floor, in a position with good air circulation, to sense room temperature. IMPORTANT Do not mount the device where it can be affected by: 1.Drafts or dead spots behind doors or in cor- ners. 2.Hot or cold air from ducts. 3.Radiant heat from the sun or appliances. 4.Unheated (uncooled) areas such as an outside wall behind the thermostat. 5.Concealed pipes or chimneys. Mounting and Wiring CAUTION Equipment damage hazard. Operation at low temperatures can cause fan coil damage. This thermostat is not a safety device. Do not use it where the space temperature is outside of the device operating range. A display of two dashes, – –, for the Room Temp display indicates a sensor failure or a temperature outside of the thermostat operating range of 18°C to 49°C (0°F to 120°F). With – – displayed, the thermostat ceases to operate. When the temperature returns to within its operating limits, the thermostat returns to operation. The optional freeze protect feature should be used if low temperatures can occur. Models ApplicationsFeatures Heat/Cool/ Auto PipesVoltageNumber of Relays a a The five relays are wired via terminals W, Y, Gh, Gm, and Gl. Relay 1 controls Heat open (W) or Cool open (Y). Relay 2 controls Cool open or Electrical heater output (Y/A). Relays 3, 4, and 5 control the High, Medium, and Low fan speeds respectively (Gh, Gm, and Gl). NOTE: In 2-pipe configurations without Auxiliary Heat, only 4 relays are used; relay 2 (Y/A) is not used.

The pipe sensor will sense the temperature in the pipes to tell the thermostat when the system is set to Heat or Cool. 1.Check Installer Setup number (IS) 5 to ensure it is set to the desired value. (See Table4 on page12). 2.Wire pipe sensor to Sc and Ps terminals. 3.Attach pipe sensor to bottom side of the pipe with the leads pointing down. 4.Insulate pipe sensor, as necessary. 5.Change pipe sensor thresholds for cooling or heating by setting Installer Setup Numbers (IS) 6 and 7 to desired values. Remote Temperature Sensor Wiring The TR21 is an optional remote temperature sensor that can be used as an alternative to the internal sensor. In addition to the TR21, other Honeywell sensors that use a 20k Ohm curve may be used as the remote sensor. WARNING Risk of electrical shock. Can cause severe injury, property damage or death. Disconnect power supply before servicing. CAUTION Erratic system operation hazard. Failure to follow proper wiring practices can introduce disruptive electrical interference (noise). Keep wiring at least one foot away from large inductive loads such as motors line starters, lighting ballasts, and large power distribution panels. Shielded cable is required in installations where these guidelines cannot be met. Ground shield only to grounded controller case. IMPORTANT All wiring must comply with local electrical codes and ordinances or as specified on installation wiring diagrams. —Wall module wiring can be sized from 16 to 22 AWG (1.31 to 0.33 sq. mm) depending on the application. —The maximum length of wire from the thermo- stat to a wall module is 1000 ft. (305 m). —Twisted pair wire is recommended for wire runs longer than 100 ft. (30.5 m). 1.Check Installer Setup Number (IS) 4 to ensure it is set to use the remote sensor. (See Table4 on page12). 2.Wire sensor to Rs and Sc thermostat terminals. 3.Push excess wire back into the hole. Plug the hole using non-hardening caulk, putty or insula- tion to prevent drafts from affecting perfor- mance. 4.Remove sensor cover. 5.Mount sensor to the wall or junction box using the screws and anchors provided. 6.Level the sensor for appearance only. Device functions correctly even when not level. 7.Replace sensor cover. NOTE:For complete wiring instructions, please follow the installation instructions provided with the remote sensor.
