PECO TW180 Thermostat Instruction Manual Overview

Summary of Contents

• Page 1: TW180 thermostat is intended for use in commercial and residential environments. It supports both programmable and non-programmable operation. Read these instructions carefully before attempting to install, operate or service this thermostat. Failure to observe safety information and comply with instructions could result in personal injury, death and/or property damage. Key features include auto-changeover, optional remote sensor, and three levels of keypad lockout with optional PIN access code. The PECO TW180 applications include fan coil, PTAC and conventional systems with single or multi-speed fan operation. Retain these instructions for future reference. This product, when installed, will be part of an engineered system whose specifications and performance characteristics are not designed or controlled by PECO. Temperature control range is 50 to 90°F (10 to 32°C) with a differential of 1°F. Operating humidity is 5%-95% RH, non-condensing. Combined load current not to exceed 20 amps.
• Page 2: Installation This thermostat is intended for indoor use only. Part III: Set clock, month, and day When power is first applied to the thermostat, it will activate the clock display. It is recommended that time and day are entered before performing advanced configuration. Select an appropriate thermostat location Locate the thermostat about four feet (1.2m) above the floor on a wall with good ventilation. Required components (not included, unless otherwise specified): System test verification is highly recommended to verify thermostat operation. Part I: Removal of old thermostat Turn off power to thermostat at main fuse or circuit breaker box. Remove the front cover of the old thermostat. Part V: Remove battery insulator tab Remove insulator tab after power is applied.
• Page 3: Thermostat programming allows for easy switching between non-programmable and programmable modes in Service Menu 100. In non-programmable mode, the thermostat controls to a single setpoint with a dead band for auto changeover from heat to cool. The TW180 can be configured for summer and winter operation using a pipe temperature sensor or an aquastat. Service Menu 171 sets the operation for 2-pipe or 4-pipe fan coil systems. A damper output is available when the brown lead is not used for stage 2 heat, with operation determined in Service Menu 111. Fan operation can be configured in Service Menu 350 with options for ON, AUTO, or Staged. Occupancy input can be standalone or used with a door switch, affecting the thermostat's operation based on occupancy detection. The TW180 can automatically change from summer to winter operation based on water temperature in the main piping riser. Service Menus allow configuration for occupied duration, setback ramping, and nighttime lock settings. The keypad lockout function restricts access to features, with three levels of lockout available in Service Menu 340.
• Page 4: Advanced configuration service menus The following service menus commonly require configuration. Please verify that these are set for your specific application. SM 100 = Programmable or Nonprogrammable SM 110 = System Type SM 120 = Fan Control for Heating SM 135 = W1 Heat Output NO or NC SM 170 = Remote Sensors SM 240 = Number of Programmable Events per Day SM 395 = Override Duration for Programmable Operation SM 340 = Keypad Lock Out Service menu access Hold lower right and lower left keys for five seconds. Press Next or Go Back button to select a service menu. Press ▲/ ▼ to select option. Press Done when complete. Schedule format options include nonprogrammable, 5-1-1 schedule mode, and 5-2 schedule mode. Daylight savings time follows the US 2007 format when enabled. System type options include various heating and cooling configurations. Fan control options determine how the thermostat activates the fan with heating demand. Remote sensor input options include no remote sensors, remote indoor sensor connected, and sensor averaging. Pipe sensor operation can be enabled for two-pipe or four-pipe systems.
• Page 5: Pipe sensor purge options are available when SM 171 is set to 1 or 2. The purge continues until a non-ambiguous condition is sensed or a 3-minute purge is initiated. Fault detection can be disabled or configured to activate on door open or close. The number of program events can be set to 2 or 4, with OCC1, UNOCC1, OCC2, and UNOCC2 as event types. Clock format can be set to display temperature in Fahrenheit or Celsius. Fan off delay settings determine how long the fan runs after heating or cooling outputs are disabled. Temperature range settings allow for low and high selectable temperature setpoints. Occupancy sensor and door switch options can be enabled or disabled, with various configurations available. Nighttime lock can be enabled to keep the thermostat in occupied mode during specified times. Keypad lockout options restrict access to certain features while still allowing access to the service menu.
• Page 6: Fan mode options include ON, Auto, and Staged Only, with user selections based on fan speeds. System mode settings allow for OFF, Heat, Cool, and Auto selections. Controlled Off enables the unit to control to the Setback setpoints while in off mode. Flush function for fan coil systems should be set to 0 unless connected to hydronic valves to prevent equipment damage. Minimum dead band adjustment prevents short cycling between heating and cooling modes. Pre-occupancy purge energizes the lowest fan available prior to scheduled events. Temporary occupied duration limit sets the duration of user override for programmable operation. Minimum off time sets the minimum off duration for heat and cool output. Programmable and intermittent fan modes determine fan operation during occupied and unoccupied periods. Default display icons can be customized based on user preferences.
• Page 7: Heating system output test options include disabling, first stage heat, and second stage heat or damper. Fan system output test can be enabled based on service menu settings. Outputs will be activated for 10 minutes when enabled. The outputs will automatically turn on after activation. Copyright information is provided for PECO, Inc. Document version is REV 04.

• Page 8: Troubleshooting & frequently asked questions In case of difficulty, try one of the following suggestions below. If display screen is blank, check to assure proper wiring of power to the thermostat. Check power to verify that there is power (24-277 VAC) available. If keys do not allow manual entry, access Service Menu 340 to assure there is no keypad lockout. Dashes in the temperature display indicate a remote probe error. Err in clock display indicates a service fault input. If no heating or cooling is running, check Service Menu 110 to assure that the correct option is selected to match the system type. If heating or cooling system doesn’t respond, check Service Menus 110 and 120 to assure that the correct option is selected. If demand indicator light is red, heating is occurring and no action is required. Menu item not available may indicate some service menus are disabled when not in use. Red LED is flashing and a code is displayed in the clock location indicates a fault is present on TB1-3 and TB1-7.
