Introduction

Program Features

The microprocessor controller offers improved control through easy monitoring and adjustment of unit parameters by way of a lighted graphical display and a push-button keypad.

Pre-Programmed Operating Sequences

The controller has been pre-programmed to offer multiple control sequences to provide tempered air. Factory default settings allow for easy setup and commissioning. The sequence parameters are fully adjustable. Refer to the Sequence of Operation beginning on page 2 for details.

BMS Communication

With the addition of an optional BMS Communication card, the user can remotely adjust set points, view unit status points and alarms. The microprocessor controller is capable of communicating over several protocols:

• BACnet® MSTP • LonWork®

• BACnet® IP/Ethernet • Modbus

See Points List on pages 36 and 37 for a complete list of BMS points.

Internal Time Clock

The controller has an internal programmable time clock, allowing the user to add up to seven different occupancy schedules. The user may also add Holidays for additional energy savings. The time clock option

also has morning warm-up capability for optional comfort at the time of occupancy.

Alarm Management

The microprocessor controller will monitor the unit conditions for alarm conditions. Upon detecting an alarm, the controller will record the alarm description, time, date, available temperatures, and unit status for user review. A digital output is reserved for remote alarm indication. Alarms are also communicated via BMS (if equipped).

Occupancy Modes

The microprocessor controller offers three modes of determining occupancy: a dry contact, the internal time clock or the BMS. If in the Unoccupied mode the unit will either be shut down, or will cycle on to maintain adjustable unoccupied room temperature and humidity set points.

Remote Display Panel (Optional)

A touchpad display panel allows for remote monitoring and adjustment of parameters, allowing ease of control access without going outdoors.

WARNING

Electrical shock hazard. Can cause personal injury or equipment damage. Service must be performed only by personnel that are knowledgeable in the operation of the equipment being controlled.

The microprocessor controller can be configured for air handler, energy recovery, dedicated outdoor air system and make-up air applications. Each application utilizes similar technologies for heating and cooling: chilled water, hot water, indirect gas, electric heat, packaged DX cooling, and packaged DX cooling with digital scrolls. All set points, lockouts and delays are user adjustable via the keypad display.

General Operation

UNIT START COMMAND: The microprocessor

controller requires a digital input to enable operation. The unit can then be commanded on or off by this digital input, the BMS or internal time clock.

• Initial delay

• Factory mounted and wired dampers are powered, if equipped. (Outdoor air, exhaust air, and recirculation air dampers).

• Exhaust fan and energy recovery wheel start after a 10 second delay, if equipped.

• Supply fan starts 15 seconds after the exhaust fan.

• Tempering operation begins (see modes below).

UNIT STOP COMMAND (OR DE-ENERGIZED):

• Supply fan, exhaust fan, tempering, and wheel are

de-energized.

• Outdoor air and Exhaust air dampers are closed after a 10 second delay. Recirculation air dampers spring open.

OCCUPIED/UNOCCUPIED MODES: The microprocessor controller offers three modes of determining occupancy: a dry contact, the internal time clock or the BMS. When in the unoccupied mode, the unit can be configured to shut down, or cycle on to maintain the unoccupied room set points. The unit can be temporarily overridden to the occupied mode via a digital input or the keypad display.

The internal time clock can be configured with morning warm-up to bring the space to the occupied set point prior to occupancy.

• Occupied Mode:

- Exhaust fan on, if equipped

- Supply fan on

- Heating (refer to Heating section)

- Cooling (refer to Cooling section)

- Energy Recovery Wheel control (refer to

Energy Recover Wheel section), if equipped.

- Damper control (refer to Outdoor Air and

Recirculated Air section), if equipped.

• Unoccupied Mode (Unit Off): Unit remains off when in unoccupied mode.

• Unoccupied Mode (Cycle on Room): Optional unoccupied mode when there is an unoccupied recirculation damper and room temperature and/ or humidity sensor(s) connected to the controller. The unit will cycle on to maintain unoccupied room set points if there is a call for unoccupied heating, cooling or dehumidification.

DDC Controller for Tempered Air Products

Sequence of Operation

- Exhaust fan off, if equipped.

- Supply fan off.

- Recirculation air damper open.

- OA damper closed.

- Tempering operations begin (see modes below)

Set Point Control (Occupied)

Supply air temperature set point can be configured as constant, or can be reset by either outside air temperature, or room temperature set point. If equipped with BMS communications, the user can also directly command the supply temperature set point, or room temperature set point (if equipped with a room temp sensor).

• Outdoor Air Temperature Reset Function: The controller will default to supply temperature reset based on outdoor air temperature. The controller will monitor the OA temperature and reset the supply temperature set point based upon the outdoor air reset function.

• Room Temperature Reset (optional): With a room temperature sensor, the controller will adjust the supply air temperature set point between the minimum (55°F) and maximum (90°F), to satisfy the desired room temperature.

Set Point Control (Unoccupied)

When equipped with an unoccupied recirculation damper and optional room temperature and/or humidity sensors, the unit will cycle on to maintain the unoccupied room set points.

• Unoccupied Heating: If equipped with heating, the unit is enabled when the room temperature is less than the unoccupied heating set point minus differential (65°F-5°F). The supply air temperature set point will be set to the supply maximum reset limit (90°F). The unit cycles off when the room temperature reaches the unoccupied heating set point.

• Unoccupied Cooling: If equipped with cooling, the unit is enabled when the room temperature is greater than the unoccupied cooling set point plus differential (80°F+5°F). The supply air temperature set point will be set to the supply minimum reset limit (55°F). The unit cycles off when the room temperature reaches the unoccupied cooling set point.

• Unoccupied Dehumidification: If equipped with cooling, the unit is enabled when the room relative humidity exceeds the unoccupied room relative humidity set point plus differential (50%+5%), or when dehumidistat contact indicates excessive humidity. The supply air temperature set point will be set to the equivalent occupied supply set point.

• Morning Warm-Up: The unit uses an algorithm involving space temperature and the heating /cooling

rate of the previous day to determine the time required to efficiently temper the space to occupied set point prior to occupancy.

Heating

The heating is controlled to maintain the supply temperature set point. The heating will be locked out when the outside air temperature is above the heating lockout (70°F).

• Indirect Gas Furnace: Microprocessor controller will modulate the indirect gas furnace to maintain the supply temperature set point.

• Hot Water Coil: Microprocessor controller will modulate a hot water valve (provided by others) to maintain the supply temperature set point. Coil

freeze protection must be provided by others in the field!

• Electric Heater: Microprocessor controller will modulate an electric heater to maintain the supply temperature set point.

• Heat Pump: Microprocessor controller will stage compressor(s) to maintain the supply air set point. This signal will come wired to the factory provided heat pump module. All external water valves and

valve controls are provided, wired and mounted by others in the field, including freeze protection.

Cooling

The cooling is controlled to maintain the supply temperature set point. The mechanical cooling will be locked out when the outside air temperature is below the cooling lockout (55°F).

• Chilled Water: Microprocessor controller will modulate a chilled water valve (provided by others) to maintain supply air set point. Coil Freeze protection

must be provided by others in the field!

• Packaged DX Cooling (Standard Scroll): Microprocessor controller will control stages of cooling to maintain the supply air set point.

• Packaged DX Cooling (Digital Scroll): Microprocessor controller will modulate the digital scroll to maintain the supply air temperature set point.

• Heat Pump: Microprocessor controller will power the reversing valve within the heat pump module to direct the refrigerant flow for airside cooling. The cooling is controlled to maintain the supply temperature set point. All external water valves and

valve controls are provided, wired and mounted by others in the field, including freeze protection.

DDC Controller for Tempered Air Products

Economizer

If the application requires cooling, and the outdoor air conditions are suitable for free cooling, the controller may enter the economizer state. If the unit is economizing and the discharge temperature set point is not being met, the controller may bring on mechanical cooling. If equipped with a modulating outdoor air and recirculated air damper, the dampers will modulate between the minimum OA and maximum positions to maintain the supply temperature set point. If equipped with an energy wheel, see Energy Recovery Wheel Sequence.

• Temperature: The economizer will be locked out when:

- The outside air is less than the economizer low

lockout (40°F).

- The outside air is greater than the economizer

high lockout (65°F).

- The unit is operating in dehumidification mode.

- There is a call for heating.

• Temperature/Dew Point: The economizer will be locked out when:

- The outside air is less than the economizer low

lockout (40°F dry-bulb).

- The outside air is greater than the economizer

high lockout (75°F dry-bulb).

- The outside air is greater than the economizer

high dew point lockout (55°F dew point)

- The unit is operating in dehumidification mode.

- There is a call for heating.

Dehumidification

The cooling is controlled to maintain the cold coil set point. The dehumidification sequence will be locked out when the OA is less than the dehumidification lockout (10°F) above the cold coil set point. If equipped with BMS communications, the user can also directly set the cold coil leaving air set point.

• Optional Room Dehumidistat: The room dehumidistat is a field mounted sensor that monitors the relative humidity (RH) of the room. If the RH exceeds set point, the dehumidistat will reset the cold coil set point to the minimum (50°F). Once the room dehumidistat is satisfied, the cold coil set point will return to the maximum (55°F).

• Optional Room Relative Humidity Sensor: The controller will adjust the cold coil leaving air temperature set point between the minimum (50°F) and maximum (55°F) set points, to satisfy the desired room relative humidity set point.

Reheat

While the unit is in dehumidification mode, the supply air can be reheated via Primary Heating Source, On/Off Hot Gas Reheat or Modulating Hot Gas Reheat.

• Primary Heating Source: The main heating source is enabled to reheat the air to meet the supply temperature set point. (Except heat pump). The

DDC Controller for Tempered Air Products

primary heat source may also be configured to act as secondary reheat.

• Modulating Hot Gas Reheat (bypass damper): The microprocessor controller will open the On/Off hot gas reheat valve, and modulate the Hot Gas Reheat bypass damper to maintain the supply temperature set point.

• Modulating Hot Gas Reheat (valve): The microprocessor controller will modulate the hot gas reheat valve to maintain the supply temperature set point.

• On/Off Hot Gas Reheat: The microprocessor controller will open the On/Off hot gas reheat valve to maintain the supply temperature set point.

Supply Fan VFD Sequence

If the factory has installed a VFD and wired it to the controller, it is intended to operate at a constant speed during operation. This speed needs to be set during test and balance of the unit. If equipped with BMS communications, the user can also directly command the supply fan speed.

• Optional Room CO2 Sensor: The controller will modulate the supply fan based upon a comparison of the CO2 set point to the actual CO2 levels reported from the sensor. Mechanical high static

protection cutoffs must be installed by others to protect the system and equipment from over-pressurization.

• Optional Duct Static Pressure Sensor: The controller will modulate the supply fan based upon a comparison of the duct static pressure set point to the actual duct static pressure level reported from the sensor. Mechanical high static protection

cutoffs must be installed by others to protect the system and equipment from overpressurization. The manufacturer does not assume responsibility for this.

• Optional Building Static Pressure Sensor: The controller will modulate the supply fan based upon a comparison of the building static pressure set point to the actual building static pressure level reported from the sensor.

• Optional Single Zone VAV (SZ): The controller will control the supply air temperature and supply fan speed to maintain the room temperature set point. This sequence requires a room temperature sensor. Heating - When the room requires heating, the controller will reset the supply air temperature set point up to the maximum (90°F) while increasing the supply fan speed up to its maximum heating speed. Cooling - When the room requires cooling, the controller will first reset the supply air temperature set point down to the minimum (55°F) while the supply fan remains at the minimum cooling speed. After a time delay, the supply fan speed will increase up to its maximum cooling speed to maintain the room temperature set point.

Exhaust Fan VFD Sequence

• Optional Building Static Pressure Sensor: The controller will modulate the exhaust fan based upon a comparison of the building static pressure set point to the actual building static pressure level reported from the sensor.

• Optional Supply Fan Tracking: The controller will proportionally modulate the exhaust fan based upon the supply fan speed.

• Optional Outdoor Air Damper Tracking: The controller will proportionally modulate the exhaust fan based upon the outdoor air damper position.

Outdoor Air and Recirculated (Recirc) Air Damper Control

If equipped with a modulating outdoor air and recirculated air damper, the recirculated air damper will operate inverse of the outdoor air damper. The outdoor air damper will open to a Minimum Outdoor Air Position (Min OA) when in occupied mode. If the controller is configured to modulate the supply fan speed, the minimum and maximum OA positions can be reset based on supply fan speed. If equipped with BMS communications, the user can also directly reset the damper position up to the maximum OA position.

• Optional Room CO2 Sensor: The controller will proportionally modulate the OA/RA dampers based upon a comparison of the CO2 set point to the actual CO2 level reported from the sensor. As the CO2 level rises, the controller will proportionally modulate the outdoor air damper open, between the minimum and maximum OA position.

• Optional Building Pressure: The OA/RA dampers will modulate based upon the signal from a building static pressure sensor. The controller will modulate the dampers, between the minimum and maximum OA positions, based upon a comparison of the building static pressure set point to the actual building static pressure level reported from the sensor.

Energy Recovery Wheel Sequences

Economizer (optional): If the unit is equipped with an

energy recovery wheel, the economizer will modulate/ stop the energy wheel to achieve free cooling.

• Stop Wheel: When economizer mode is enabled and there is a signal for cooling, the wheel will stop rotating to allow free cooling.

• Modulate Wheel: When economizer mode is enabled and there is a signal for cooling, the

controller modulates wheel speed to maintain the supply temperature set point.

• Energy Wheel Bypass Dampers (optional): During normal operation, the dampers shall remain closed to allow full operation of the energy wheel. During economizer sequences, the dampers will be open to bypass the energy wheel.

Frost Control (optional): The microprocessor controller will activate the frost control method when the outdoor air temperature is less than the defrost set point (5°F) and the wheel pressure switch is closed, due to a high wheel pressure drop. Once either the pressure drop decreases below the pressure switch point, or the outdoor air temperature increases, the unit will resume normal operation.

• Electric Preheater: When frosting is occurring, the preheater is energized to defrost the wheel.

• Modulate Wheel: When frosting is occurring, the wheel slows to allow defrosting to occur.

• Cycle Wheel: When frosting is occurring, the energy wheel is cycled off for a defrost cycle time (2 minutes). After the defrost cycle time, the wheel is re-energized to continue normal operation. The controller will not allow another defrost cycle for a minimum normal operating cycle time (5 minutes).

• Timed Exhaust: When frosting is occurring, the supply fan is cycled off along with the tempering for a defrost cycle time (5 minutes). The exhaust fan will continue to run, allowing the warm exhaust air to defrost the wheel. After the defrost cycle time, the supply fan and tempering are re-energized to continue normal operation. The controller will not allow another defrost cycle for a minimum normal operating cycle time (30 minutes).

Alarms

The microprocessor controller includes a digital output for remote indication of an alarm condition. Possible alarms include:

• Dirty Filter Alarm: If the outside air or return air filter differential pressure rises above the differential pressure switch set point, the microprocessor controller will activate an alarm.

• Supply and Exhaust Air Proving Alarm: Microprocessor controller monitors proving switch on each blower and displays an alarm in case of blower failure.

• Sensor Alarm: Microprocessor controller will send an alarm if a failed sensor is detected (temperature, pressure, relative humidity).

• Supply Air Low Limit: If the supply air temperature drops below the supply air low limit (35°F), the microprocessor controller will de-energize the unit and activate the alarm output after a preset time delay (300s).

• Other Alarms: Wheel Rotation, High Wheel Pressure, High/Low Refrigerant Pressure.

HEAT AND REHEAT OPERATION IS DISPLAYED. (IF EQUIPPED)

Heater Control displays the proportional percentage of the heater analog output.

Electric Heater: The Heater Control % is proportional to the 0-10 VDC signal being sent to the SCR controller, located in the electric heater control center. 0% Heating = 0 VDC - 0 kW output

100% Heating = 10 VDC - Max kW output

Hot Water: The Heater Control % is proportional to the 0-10 VDC signal being sent to the heating control valve (BY OTHERS). The heating control output can be configured to DIRECT / REVERSE acting, along with the minimum and maximum output voltages by entering the MANUFACTURER menu. 0% Heating = 0 VDC

100% Heating = 10 VDC

Indirect Gas: The Heater Control % is proportional to the 0-10 VDC signal being sent to the indirect gas furnace controller, located in the indirect gas control center. The first stage is on at 1% Heater Control. The furnace will then modulate proportionally from minimum to maximum capacity. 0% = 0 VDC – OFF 1% = 0 VDC – MINIMUM TURNDOWN ENABLED 1 - 100% = 0 - 10 VDC = FURNACE MODULATION

Heat Pump Heating: The Heater Control % displays internal heating ramp as a percent. Compressor operation is displayed when engaged.

• 1 = First Staged Compressor Operation

• 2 = Second Staged Compressor Operation

Hot Gas Reheat:

If hot gas reheat is staged control:

“Staged reheat is: ON/OFF” will indicate operation.

If hot gas reheat is modulating bypass damper control:

0% = OFF 1% - 100% = 4 - 10 VDC = AIRFLOW DAMPER MODULATION

If hot gas reheat is modulating valve control:

0% = OFF 1% - 100% = 0 - 10 VDC = HOT GAS REHEAT VALVE MODULATION
