TSTBT4H2CP SERIES

3

The Bosch TSTBT4H2CP Thermostat Series consists of

4-wire MODBUS communicating thermostats. Utilizing

RS485 MODBUS protocol, the TSTBT4H2CP Thermostat

Series can communicate with the equipment, monitor the performance, and report the status of the equipment.

The MODBUS protocol is received and then translated to pulses to be received by the HVAC equipment. This translation is performed by the TRM (Transmitting and

Receiving Module). The thermostat and TRM communicate via 2 wire MODBUS, the TRM and the HVAC equipment communicates via 4-12 wires utilizing pulses.

The Bosch TSTBT4H2CP Thermostat Series communicates utilizing MODBUS protocol to the TRM

Caution

A trained, experienced technician must install this product. Carefully read these instructions. You could damage this product or cause a hazardous condition if you fail to follow these instructions. See the product specifi cations at the end of this manual prior to installing.

To insure a solid fi t between the thermostat and the subbase:

1. Mount subbase to a fl at wall

2. Use screws provided

3. Drywall anchors should be fl ush with the wall

4. Wires should be pushed into the wall

wall loCaTions

Do not install thermostats in locations that are:

• On an exterior Wall

• In direct sunlight

• Where there may be concealed chimneys or pipes behind the wall

• Close to a window or door leading outside

• Close to objects radiating heat such as fi re places, lighting, space radiators, or any other applicance

• In areas that do not require conditioning

• In dead spots or where drafts can occur (behind doors or in corners)

• Close to hot or cold air ducts

Pick an installation location that is easy for the user to access. The temperature of the location should be representative of the building.

First, separate the thermostat and sub-base using a fl at blade screw driver as shown below.

insTallinG The Trm reCeivinG module

TRM communicates with the TSTBT4H2CP Thermostat

There are two LED lights on the TRM. One is the COM light which blinks green when communication is happening between the TRM and the thermostat. This light will normally blink about every 10 seconds as the thermostat and TRM are in constant communication for status updates. If communication is lost for more than 10 minutes, the COM LED will become red. A certifi ed licensed technician should be called to service the system if this occurs.

The other LED is labeled HVAC. This light indicates if the unit is actively heating or cooling. If the unit is cooling, then the

LED is yellow, if the unit is in heating, then the LED is red. If the thermostat is satisfi ed, then the LED if off.

TSTBT4H2CP Thermostat Series Wiring

Notes: Bosch Water Source Heat Pumps utilize “O” type reversing valve operation. If your heat pump utilizes “B” type reversing valve operation, substitute the wiring for the

“O” terminals for “B”.

TemPeraTure sensor ConneCTions zonb-las---m--a return air

Temperature sensor

Optionally, a temperature sensor can be installed in the return air duct. This sensor is automatically detected by the TRM and used to control the equipment should the communication between the thermostat and TRM fail.

This insures the indoor temperature does not drop below

55°F or rise above 85°F.

Use AWG 18–22 thermostat wire to connect the sensors to the TRM.

Ts1 and Ts2

Temperature sensor 1 and Temperature sensor 2 inputs on the TRM can be confi gured in the thermostat setup menu as an outdoor temperature sensor, a leaving air temperature sensor, or as a remote room temperature sensor.

Either TS1 or TS2 can be designated as the outside air temperature sensor, however once one of the input sensors are designated as the outdoor temperature sensor, the option will not be available for the other sensor input in the menu setup. The same logic applies for the leaving air temp. You cannot have two sensor inputs designated as outdoor temperature or leaving air temp.

For the remote room temperature sensor function, either

TS1 or TS2 can be desingnated or both can. Two remote room temp sensors are allowed.

Ts1 used as outdoor Temperature sensor

An outdoor temperature sensor is required for dual fuel heal pumps and for automatic emergency heat activation in cold weather. The sensor should be installed under the eves and in the shade.

A sensor can be installed in the supply duel to monitor the

Leaving air temperature for monitoring equipment performance. The stainless steel tube should inserted in the duct down stream from the plenum.

Ts1 used as a remote space

Temperature sensor

A sensor can be installed in a remote location, such as the second floor, and the temperature at the remote sensor will be averaged with the sensor in the thermostat when controlling the heating and cooling.

When both TS 1 and TS2 are used as remote space temperature sensors, both sensor readings will be averaged with the thermostat sensor reading.

See the available accessories at the end of this manual for compatibility, part numbers and descriptions for ordering.

remove The baTTery Tab

The TSTBT4H2CP-M--A Thermostat Series has a coin cell battery for maintaining the clock, schedules, and user settings during power outages. After the wiring of the installation, remove the battery tab. Do not remove the tab until the Receiving Module, Thermostat and equipment wiring is complete.

Some days may require a different schedule program; whether it be a different time period definition or different heating / cooling set points. To create specific schedules for specific days, continue from the Schedule

Programming Steps 1-11 from above and continue with the following instructions. Each day can have its own unique programmed schedule and set points; for a total of 7 possible unique schedules for the TSTBT4H2CP

Thermostat Series.

The decision to be made here is what days the scheduled program will be assigned to; this is accomplished by removing the days that the program will not be associated with. The remaining days being displayed are the days that the current schedule will be assigned to.

Picking up after step 11 from above:

1. Verify that the thermostat mode is in “COOL”. If not, push the SYSTEM button until “COOL” is displayed.

2. Verify the set point temperature is not higher than the space temperature. If it is, use the (down) button to adjust the set point to below the space temperature to initiate a cooling call.

1. Verify that the thermostat mode is in “HEAT”. If not, push the SYSTEM button until “HEAT” is displayed.

2. Verify the set point temperature is not lower than the space temperature. If not use the (up) button to adjust the set point to above the space temperature to initiate a heating call.

Once the space temperature matches the set point temperature on the thermostat, the heating or cooling call is removed and the equipment turns off. If the user changes the set point temperature within the minimum off time, the equipment will not come on. This is a protection feature for the compressor and is normal.

Wait 10 min and verify if equipment has began operating in heating or cooling mode. If unit remains off, call a licensed technician.

Call a technician as the thermostat must be set up correctly. There are many settings to be made and should only be attempted by a trained technician.
