Overview

The ComfortVu BACnet Thermostat Standard Model TB-24-HM can be used:

 As a stand-alone thermostat that can control equipment using built-in logic  As part of an MS/TP network of BACnet Thermostats that can be managed from a BMS front-end system  As part of a BACnet MS/TP network connected to an Carrier BACnet router in an i-Vu

provide trending and alarming of the BACnet Thermostat’s data.

The TB-24-HM thermostat has a white plastic enclosure with an LCD display and buttons for user control. It has on-board temperature, humidity, and motion sensing, and its on-board inputs and outputs are used to control equipment and optional external sensing devices. Inputs and outputs are configured using DIP switches and jumpers. The TB-24-HM thermostat requires 24 Vac power.

Economy mode

Activate Economy mode by triggering a window contact, door switch,

key-tag, remote economy switch, the built-in PIR sensor (passive infrared sensor), or through communication – binary value “UnoccupiedByNetwork”.

When Economy mode is active, the thermostat will use special

economy setpoints for cooling and heating set by technician.

See objects “EconomySetpointinHeat” and “EconomySetpointinCool” in the Technician Settings section of this manual.

Freeze Protection

Economy by window contact

Economy by built-in PIR, by the remote economy switch, or through communication

Economy by door switch

Economy by Key-tag

The Freeze protection feature will not allow the room temperature to drop below predefined cut-in temperature. Depending on which configuration the system is operating under (W/WO Heat pump), this feature will force the system to operate in heat mode and activate the fan. This feature will take effect when the thermostat is either ON or OFF. When the room temperature rises above the predefined cut-out temperature, the thermostat will return to its previous state. When freeze protection is activated, the display alternates between “AL” and room temperature.

Operating instructions (cont.)

Economizer

Economizer is used to reduce the energy consumed by the cooling systems, by using low external air temperatures to assist in the

chilling process. When outdoor temperatures are lower relative to indoor (room) temperatures, the system utilizes the cool outdoor air

as a free cooling source.

The outdoor temperature (Teconomizer) triggering the activation of the economizer, can be measured by the temperature sensor

connected to T1,0 terminals (technician parameter P08="05") or by setting a temperature value manually through communication -

AV#129 "TEconomizerEffective".

When getting the temperature through communication, terminals T1,0 can be used for any other functionality like External sensor/Soft

start in heat sensor/Deicing in cool/Door switch/Key tag.

Whenever there is demand for cooling and the outdoor temperature conditions allow the operation of the economizer, it will operate

together with the regular cooling system and will not replace it.

Economizer will start when both of the following conditions are satisfied:

Teconomizer temperature < Room temperature -

Room Temperature > Setpoint temperature

Cool differential band

Economizer will stop when the following condition is satisfied:

Room Temperature < Setpoint temperature -

Weekly program

General

Prior to programming, make sure that Technician Settings P107, P108, and P109 are configured correctly.

Program types

The thermostat can be configured to run four different types of weekly programs (set by Technician Setting P107):

 7-day program with same settings for all days.

 7- day program with different settings for each day of the week.

 One schedule for the weekdays (Monday to Friday), one for Saturday, and another for Sunday.

 One schedule for the weekdays (Monday to Friday) and another for Saturday and Sunday.

Daily events

Each daily program can use 2 or 4 schedule events per day (set by Technician Setting P108).

There are two options for settings the schedule events (set by Technician Setting P109):

 “EU Type” - Start time and Stop time

 “US Type” - Start time, setpoint temperatures, system mode, and fan speed

Enabling/Disabling/Overriding the program

Select “00” in Technician Setting P107 to disable programming capabilities.

The occupant can temporarily change the setpoint temperature to be different than the setpoint temperature specified by the program.

Changes will be effective until the next program event begins.

MAC Address and BACnet Device Instance Number

MAC Address

To set the communication MAC Address:

1. Adjust the setpoint temperature to 11ºC or 52ºF.

2. Press and hold the [C/F] button for 10 seconds to enter MAC Address configuration mode.

3. Use the [+] or [-] buttons to define the MAC Address (range 1...127).

4. When finished, press the [On/Off] button and readjust the setpoint.

5. Switch power supply off and on again for the MAC address changes to take effect.

Caution: Do not use the same MAC address for two devices on the same communication line!

MAC Address

1...127

BACnet Device Instance Number

By default, the BACnet Device Instance Number is generated automatically by the thermostat (Vendor ID + MAC address). For example, Carrier’s vendor ID is 16, and if the MAC address is 075, the BACnet Device Instance Number is 16075. Note: If you change the MAC address, you must cycle the thermostat’s power to reset the BACnet Device Instance Number.

You can override the automatically-generated BACnet Device Instance Number using the i-Vu application, an Analog Network Output microblock in a control program, or some other BACnet utility. Write the new BACnet Device Instance Number to the present_value property of Analog Value 42 (BACnetDeviceInstanceNumber).

Examples:

In the i-Vu application

1. Use the BACnet Discovery feature to discover the BACnet Thermostat and its BACnet objects.

2. In the navigation tree, select the Analog Value called BacnetDeviceInstanceNumber.

3. Change the Present Value field (shown below) to the desired BACnet Device Instance Number.

4. Click Accept.

In an Analog Network Output microblock

To change the BACnet Device Instance Number to 24113, the microblock’s address would be: bacnet://16075/AV:42/present_value, or bacnet://16075/BACnetDeviceInstanceNumber

Installation

Mount the BACnet Thermostat on an interior wall in the room to be controlled approximately 1.5 meters (5 feet) from the floor. Locate it

where the occupant can easily read the LCD display and use the controls, and where the built-in PIR motion sensor can easily detect

any movement in the room (see PIR detection area below). If the built-in temperature sensor is being used to measure room

temperature, place the thermostat where the temperature is representative of the general room conditions. Avoid cold or warm air drafts,

radiant heat, and direct sunlight.

Installation procedure

Prerequisite: Disconnect power to the main board before installing the unit.

A. Separate the front panel from back panel by pressing the tab located in the top of the unit and pulling the back panel off of the two

bottom tabs.

B. Do one of the following:

• If using an electrical box, mount the included wallplate to a standard 4" x 2" electrical box using the two larger mounting screws, then mount the thermostat to the wallplate using the three smaller mounting screws. Insert the screw cap into the wallplate’s bottom screw hole.

• If not using an electrical box, flush-mount the thermostat to the wall (no wallplate needed).

C. Make electrical connections as shown in the picture below and the wiring diagram on page 20.

Set DIP switch positions as explained in this manual.

D. Reattach the cover by placing it on the back panel’s two bottom tabs and then pushing the cover until the top tab clicks into its slot

on the cover.
