PELICAN TC1 Commercial Connected Thermostat Installation Guide Overview

Summary of Contents

• Page 1: Model: TC1 Commercial connected thermostat installation guide Before you start Review all instructions before starting to avoid discovering or creating any issues during installation. This thermostat is designed to be installed on 24V AC systems only. This thermostat is designed to be installed by a licensed professional. A Pelican Gateway must be used with this thermostat. The thermostat cannot be configured or managed without the gateway. Installation location Never install in an enclosed metal box or on a metal surface. Install in a location where it can communicate with the Pelican wireless mesh network. Install 48 to 60 from the floor in the room where it will be maintaining the temperature. Install on an interior wall away from doors, filing cabinets, electrical equipment, or other metal objects.
• Page 2: Turn off the power to the equipment this thermostat is going to be wired to. Either power off at the circuit breaker panel or by turning off the master power at a local disconnect. Remove the cover from the old thermostat and either take a picture or label the wires as a guide for wiring the new Pelican thermostat. Uninstall the old thermostat and set aside. This Pelican thermostat is designed to either mount flush on the wall or on a vertical 1-gang electrical box. Choose a mounting location where the thermostat is at least 48 to 60 above the floor. The thermostat should be on an interior wall where it can detect the temperature of the room it will be maintaining. Ensure the thermostat is away from sun exposure or airflow drafts. Avoid installing in direct sunlight. Do not install in a supply air stream.
• Page 3: Air blocking shield Before mounting the backplate to the wall, insert the airflow shield into the backplate to help prevent unusual airflows from affecting the thermostat’s temperature accuracy. Align the air shield with the backplate’s center hole. It will only align in one orientation, never force it into place. Press the shield into the back plate until it holds. Make sure the shield is fully inserted into the back plate for best results. Run wires into thermostat backplate. Pass the thermostat wire through the designated opening in the air shield. While modifying the air shield is not recommended, if the wire cannot be easily pulled through the provided hole, you may carefully use a box cutter or scissors to slightly enlarge the opening for better flexibility. Cuts can be made with minimal effect on the integrity of the air shield.
• Page 4: Attach thermostat backplate to wall using included screws. Drill two 3/16 holes if using drywall anchors. Install provided drywall anchors if required. Connect wires to thermostat backplate to complete installation. Refer to wiring diagrams on pages 8–15 for common thermostat wiring. Contact Pelican Support for wiring outside of this installation guide. Follow steps on page 5 for limited wiring applications without a Common [C] wire.
• Page 5: Limited wire installation may require a wiring module to control the HVAC system without new wires. At least three wires are needed between the thermostat and the wiring module. The maximum distance allowed between the wiring module and the thermostat is 500 feet. Step 1 involves removing the wiring module from the thermostat's back plate. Loosen the (R), (C), and (D) terminals on the wiring module to remove it. Step 2 requires installing the wiring module in the HVAC equipment. Secure the wiring module with a sheet metal screw. Connect the wiring module’s terminals to the corresponding low-voltage input terminals on the HVAC control board. Refer to the wiring diagrams for common thermostat wiring. Ensure to use unshielded wire for the connections.
• Page 6: Connect wiring module to thermostat using existing wires. Connect the (R), (C), and (D) terminals from the wiring module to the corresponding terminals on the thermostat's back plate. Wiring module should be mounted at the control board. Maximum wire length is 500 feet. Unshielded 18 gauge thermostat wire is recommended. Thermostat back plate should be mounted in the room.
• Page 7: Attach the display. Before attaching the display, write down the serial number displayed on the screen. Align the display with the back plate’s alignment pins, then press it into the back plate until it clicks into place. Turn on the power to the HVAC equipment connected to the thermostat. If your Pelican thermostat does not power on, refer to page 16 for troubleshooting. For instructions on setting up Conventional or Heat Pump control, refer to page 17. The thermostat has an internal locking mechanism that secures the display to the back plate. To engage the lock, insert a 1/8 flat-head screwdriver into the hole on the left side of the thermostat. Do not attempt to force the display off the back plate, as this could cause damage.
• Page 8: Wiring diagrams are provided for various systems. Refer to pages 8–9 for conventional heating and cooling systems. Refer to pages 10–11 for heat pump systems. Refer to pages 12–13 for two-pipe fan coils. Refer to pages 14–15 for four-pipe fan coils. For zone damper control, see the separate installation guide. If installations are not covered in this guide, stop installing the thermostat. Contact Pelican Sales Engineering Support for further assistance. 24 VAC terminal block designations are listed for conventional and heat pump systems. Details for two-pipe and four-pipe fan coils are included.

• Page 17: Connect to 24 VAC class 2 circuits only. Latching relays are rated for 24 VAC @ 2 amps continuous load. All wire to be installed by customer in accordance with local electrical codes. Use 18 gauge unshielded thermostat wire. If the Pelican thermostat does not power on, check that all wires are properly inserted into the terminal blocks at the thermostat and at the HVAC equipment. Use a multi-meter to ensure that 24 VAC power is being supplied by HVAC equipment. If 24 VAC is not found, check that the master power has been turned back on for the HVAC equipment or verify that the HVAC electrical breaker has not tripped. Use a multi-meter to ensure that 24 VAC power is found at the thermostat. If you used the Wiring Module, use a multi-meter to ensure that 24 VAC power is found at the Wiring Module and the thermostat. If the thermostat still does not power on, contact Pelican technical support for further assistance.
• Page 18: If the Pelican thermostat does not show up on the Pelican App, check the following: Check the thermostat upper right hand corner for connection symbols. If the thermostat is unable to connect, finish installing other Pelican devices and verify the thermostat is not in a metal enclosure. If the thermostat is connected but the gateway cannot reach the Internet, check the Pelican Gateway for installation and power. Contact Pelican technical support for further assistance if connection issues persist. To access the thermostat info, touch the icon in the upper right hand corner of the screen. The serial number is the unique identifier for the thermostat. The thermostat name is a custom identifier set using the Pelican App. The configuration identifies the thermostat’s current setup and allows changes between Conventional and Heat Pump modes.
• Page 19: Model number: This is the model number of this thermostat. Alarm notifications: If there are any icons in the upper right hand corner of the thermostat, the Info page will identify the issue detected. Thermostat conventional/heat pump configuration page: Within the first 5 minutes after the thermostat was last powered on, the thermostat allows you to set it to Conventional or Heat Pump control. To access the configuration page, select Touch to adjust and then press the icon in the upper right hand corner of the screen. Under Configuration, you will see the current control setting (default configuration is Conventional). To change the configuration, press the change button to the right of Configuration. Then touch Conventional, Heat Pump (O), or Heat Pump (B) and press Save at the bottom of the screen to set the new configuration. If you do NOT want to change the thermostat’s configuration, press Cancel at the bottom of the screen.
