Important Safety Information and Installation Precautions 9
Tc300B Thermostat User Guide
Lightning and high-voltage danger Most electrical injuries involving low-voltage wiring result from sudden, unexpected high voltages on normally low voltage wiring. Low-voltage wiring can carry hazardous high voltages under unsafe conditions. Never install or connect wiring or equipment during electrical storms. Improperly protected wiring can carry a fatal lightning surge for many miles. All outdoor wiring must be equipped with properly grounded and listed signal circuit protectors, which must be installed in compliance with local, applicable codes. Never install wiring or equipment while standing in water. Wiring and equipment separations All wiring and controllers must be installed to minimize the possibility of accidental contact with other potentially hazardous and disruptive power and lighting wiring. Never place 24VAC or communications wiring near other bare power wires, lightning rods, antennas, transformers, or steam or hot water pipes. Never place wire in any conduit, box, channel, duct or other enclosure containing power or lighting circuits of any type. Always provide adequate separation of communications wiring and other electrical wiring according to code. Keep wiring and controllers at least six feet from large inductive loads (power distribution panels, lighting ballasts, motors, etc.). Failure to follow these guidelines can introduce electrical interference and cause the system to operate erratically.

Security Requirement
Security requirement System Environmental Considerations An Internet firewall is required to isolate the Thermostat. Unprotected Internet connections can expose and damage the thermostat system and facility components to cyber-attacks from third parties. This may cause the thermostat to malfunction and can also be misused for illegal purposes for which the operator may then be held liable. Deployments and Maintenance Considerations • Always keep the local server up to date on the latest security patches via a regular system update. This applies not only to workstations or servers running on Windows, Linux, Mac, or any devices that run as part of information infrastructure or operations workstation. • Always keep the thermostat firmware with the latest released firmware to have maximum protection by built-in security features. • Do not use default passwords for any devices (if exists). This includes, but not limited, to all server workstations, storage servers, firewall devices, routers, and mobile devices. • Do not use weak passwords for server administrators or operators. Different user roles (for example administrator, user, guest, etc.) shall have a different password, and the user should not share common passwords. • In case of wireless communication, malicious wireless devices can easily scan the wireless channel and inject malicious packets or mass data flow to perform Denial-of-Service attacks. Honeywell has taken steps to prevent the TC300B Commercial Thermostat device from being injected, but the mass data flow will result in the loss of wireless communication bandwidth within the whole system. A regular check of the communication failure rate or response rate of the thermostat is helpful to discover and isolate devices being attacked and stop the physical attacks in the daily operation Network Communication Notice • To keep maximum integration compatibility with third-party devices and Fast-pack communications are un-encrypted as open protocol. Improper security protection may lead to data leakage, spoofing, and/or tampered by malicious devices and denial-of- service attacks. • To keep maximum integration compatibility with legacy devices, in-room wired devices are less secure from data confidentiality and authentication thus not-recommended for a new design. It is always highly recommended to use deep mesh wireless network communication to gain maximum protection and the latest updates. • In case of Denial-of-Service attacks, all communication channels will inevitably have a loss of bandwidth due to malicious data flow. • Connected devices may contain legacy technology, which is less secure under modern cyber-security attacks. Honeywell strongly recommends using a secured deep mesh wireless network communication. In case of legacy technology, the user needs to be aware of the risk of being tampered with or attacked. To reduce the attack surface, the user is advised to physically secure the wired communication signals or provide necessary shield on wires, or place necessary access control on accessing such communication wires.

This will help prevent the discharge air temperature from getting too hot and avoid tripping limits. Gains Throttling Range 0 to 30°F (Default 10°F) The throttling range is the amount of change in the sensed temperature required to drive the output from 0 to 100%. The throttling range must be narrow enough to provide good control without becoming unstable. The throttling range is determined by factors including, the control application, the response time of the equipment being controlled, and the control algorithm being used. The narrower (smaller) the throttling range, the more precise the control and the wider (larger) the throttling range, the more stable the control. The objective is setting the throttling range to achieve the optimum balance between precision and stability. Heating Integral Time/ Cooling Integral Time 0 to 5000 Sec (Default 2500 Sec) The amount of time the error has continued uncorrected. Integral action corrects the temperature control errors of proportional-only control, but it is slower to react to large temperature or setpoint changes Fan Delay Fan On Delay Time 0 to 30 Sec (Default 30) Fan on delay time after heating outputs are turned on. May be used to run fan after heating outputs have turned on for some times so that heating coil can warm up. Fan Off Delay Time 0 to 180 Sec (Default 120 Sec) Fan run on time after all heating outputs are turned off. May be used to run fan after all heating outputs have turned off so that the heat coil can cool down before the fan turns off. Page 88

Alarm Trigger Scenario Action Level 1 Proof of Air Flow Alarm (fan state) An input (e.g., a current switch or differential pressure switch) should be available to monitor proof of air flow in the Fan Coil Unit. When configured, the control system will check this digital input once per second. If the fan is supposed to be on but is not, an alarm should be generated. For example, users can configure a DIO/UIO terminal as a binary input to detect the fan's status. When DIO2 is set as the Fan Command, and the device sets DIO2 to 'on,' if the digital input indicates no air flow for 60 consecutive seconds, a 'Proof of Air Flow' alarm will be triggered. Depending on the alarm configuration: Page 120

When configured, the control system will check this digital input once per second. For example, users can configure a DIO/UIO terminal as a binary input to detect the water flow's status. Set DIO2 as the proof of waterflow sensor, and configure the sensor as Normally Open. When there is a heating/cooling command, and the water flow valve is none or open, if the digital input indicates 'Inactive' ('Active' if Normally Closed Sensor ) for 120 consecutive seconds, a 'Proof of Water Flow' alarm will be triggered.

6 About schedule 123 Scheduling About schedule TC300B enables you to plan operations based on the time of day and holidays. This scheduling structure allows you to control day-to-day operations with the standard schedule. The holiday schedule controls days or times when a facility is typically unoccupied. The event schedule controls periods outside normal occupied times. The holiday schedule overrides the standard schedule and the event schedule overrides the holiday and standard schedules within a schedule set. Schedules use the setpoint configuration of Occupied, Unoccupied, or Standby modes. Occupied mode treats the building space as occupied and configured with comfort setpoints. Unoccupied mode treats the building space as not occupied and configured with energy savings setpoints. Standby mode setpoints are configured in a way that the setpoints can quickly change to the Occupied mode when switched. Standby mode setpoint saves energy higher than occupied mode and lesser than the Unoccupied mode. Temporary mode allows the user to change the temperature setpoints of the Occupied mode after the user switches to the temporary mode from the Occupied mode. This is not possible in Unoccupied mode and Standby mode. When a schedule uses the Occupied mode but the Occupancy sensor reads unoccupied, then the thermostat switches automatically to the Standby mode. In other scenarios, the thermostat follows the schedule status and the occupancy sensor’s value has no impact on it. How schedules works When you set up schedules, it is important to understand the relationship of the schedules in the schedule set and how to use each one. • Standard schedule: Use the weekly schedule to program occupied and standby periods for each of the week. • Holiday schedule: Use holiday schedules to set holidays that “float” or occur on a specific date each year. Up to 10 holidays can be created. Page 124
124 Weekly schedule

• Special event: Use Special event to create up to 10 special events. Note: Holiday schedules automatically write a 12:00 AM OFF time, which is in effect unless it is overridden by an event schedule.
