Sequence of Operation Run Conditions: The unit will run according to a user definable time schedule, dry contact (physical digital input number 1), manual ON command from BACview control interface, timed local override from Zone temperature sensor or via third party front end start command (software point). When commanded to run the unit will operate in the following modes: Occupied Mode: The unit will maintain ...
Zone Temperature The occupant will be able to see the zone temperature on the sensor LCD display in addition the user will be able to see other parameters that have been configured in the controller such as alarm status, alarm codes, Inputs and outputs status among others. NOTE: These codes and values vary from version to version for additional information on what is available on the RS-Pro sensor please check its commissioning BACview manual in our web site www.fhp-mfg.com.
Freeze Protection: The unit shall shut down and generate an alarm upon receiving a freezestat status. Fan: Constant Volume In the occupied mode, the fan shall run continuously or cycle with the compressor(s) depending on fan mode settings. In the unoccupied mode, fan cycles as required for unoccupied heating and cooling setpoints while in night setback.
Modulating Re-Heat Valve: This valve is an analog device and has the capability to modulate the amount of hot gas that is allowed through the re-heat coil, thus allowing control of the discharge air temperature to a user defined setpoint. The operation is similar to the on/off control except once the space temperature is satisfied the controller will monitor the space humidity if the value is greater than the setpoint the controller will modulate the valve to meet a particular a desired discharge air temperature on zone...
The heating will be enabled whenever: The fan output is on. AND the reversing valve is in heat mode (de-energized). The cooling will be enabled whenever: The fan output is on. AND the reversing valve is in cool mode (energized). ...
The controller will only allow supplemental heating if the unit is configured to allow this operation, units equipped with hot gas re heat valves or damper control enable will not have supplemental electric heat functionality. Discharge Air Temperature: The controller will monitor the discharge air temperature to be located at discharge side of coil. If the supplemental heating is installed then sensor will be in the discharge side of heating coil.
Single Outside Air Temperature (OAT) Reset: OAT> OAT Reset °F (adj.): Controller will initiate cooling call to run compressors and modulate Re-heat Valve only when the outside air temperature is greater than 55°F (Factory Default) OAT< OAT Reset °F (adj.): Controller will initiate a call for heating.
Controller will command the unit to run full mechanical cooling operation (on units with more than two compressors please check with factory), the valve will be set for cooling operation and both first and second compressors will be commanded on, the fan will run continuously or if the unit is equipped with a Variable Frequency Drive (VFD) it will command the drive to maintain its static pressure setpoint and the re-heat valve will be modulated to maintain a 65°F (Factory Default (adj.)) discharge air temperature setpoint .

Auto Cool: Chageover Temperature > Changeover Setpoint + Change over dead Band Auto Heat: Chageover Temperature < Changeover Setpoint - Change over dead Band When using the changeover feature the system will require an air temperature sensor (10KΩ @ 77°F (25°C) Thermistor) typically located in the controlled zone.
Lead - Lag Compressor operation NOTE: This feature is only available on two stage systems. The unit will alternate the compressors by using Lead Lag control algorithm; the rotation method is user definable and can be set during the commissioning process as follows: ...
Load Water (Entering) Temperature: The controller will monitor the entering load water temperature which is located at entering side of coil. Alarms will be provided as follows: Load High Temp: If the water temperature at the entering load side is greater than the cooling setpoint plus a user definable amount (adj.), the factory default for this amount is 10°F.

RS-Sensor Termination Detail The RS Sensor is remotely mounted and installed (up to 500ft) in the zone it is recommended to use shielded cable (20AWG conductors) if installing RS-sensor only. If BACview is installed remotely using the same cable is recommended to use shielded cable (18AWG conductors).
