Specification for WSHP SmartSource ALL value for subsequent operation in the field. The brownout trip and recovery levels are a function of the application software and are listed elsewhere in this specification. d. Suction -Line Temp Sensor. Sensing element shall be equivalent to NTC Thermistor —10K ohms @ 25°C, 0.2°C interchangeability. Advanced Thermal Products — Curve Z. NOTE: The Timed (Tenant) Override switch will short out the Room sensor thermistor. Sensing range shall be 0 to 1587 with a resolution of 1°F and an accuracy of +/- 1.57 Maximum Total Error. e. Set point Adjust. The Set point Adjust circuit of a remote room sensor shall consist of a 1.5K -ohm 2 -wire potentiometer. The wiper of the potentiometer will be connected to the analog input. The other lead of the potentiometer is tied to analog common. The 0 —1.5K -ohm range will be interpreted by the base controller as an offset to the current temperature Set point -5 to +5 degrees F or a range of 55 to 95 degrees F (jumper selectable and scaled accordingly in software). f. Fan On/Auto, Heat/Cool/Auto The Room Sensor shall incorporate switches and fixed resistors that present different resistance values to a single analog input which correspond to the fan and operating mode functions detailed below. The room sensor is designed with specific resistance values to coincide with the software in unit control module. g. Temperature Input. Sensing element in the Microtechlll room temperature sensor is equivalent to NTC Thermistor —10K ohms @ 25°C, 0.2°C interchangeability. Advanced Thermal Products — Curve Z. NOTE: The Timed (Tenant) Override switch will short out the Room sensor thermistor. Sensing range shall be 0 to 158°F with a resolution of 1°F and an accuracy of +/- 1.5°F Maximum Total Error. h. Binary Inputs. 18 total (Low Pressure, High Pressure, Emergency Shutdown, 8 -Board level jumpers, 6 thermostat, Occupied/Unoccupied) that employ the Occupied/Unoccupied control. i. The Low Pressure switch shall be sourced with 24VAC or DC, +/-20%. The binary input detection circuit shall be designed such that a minimum of 7mA current flows through the external contacts. J. The High Pressure switch shall be part of an interlock circuit that interrupts power to the on -board compressor relay coil. Since this is a low voltage safety circuit as defined by UL, the designer must apply appropriate spacing as dictated by the relevant UL standards. As part of HP switch state detection, this circuit must sense the current flowing through the on -board compressor relay coil and communicate this information to the HP binary input. The current sensing circuit (Example device: NEC/CEL PS2501-1-A opto- isolator) must be upstream of the High Pressure switch, i.e., between the control output and the HP switch. In the unlikely event that the compressor binary output or HP current sensing circuit fails closed, the HP switch can still perform its intended safety function by opening the compressor relay coil circuit. k. Emergency Shutdown. This binary input will detect the presence of an earth grounded signal, which is supplied by an external, remote set of contacts — such as those provided by a Condenser Loop Water Controller. I. Unoccupied Mode. This binary input will detect the presence of an earth grounded signal, which is supplied by an external, remote set of contacts — such as those provided by a Condenser Loop Water Controller. m. Thermostat inputs G, Y1, Y2, W1, W2, shall detect the presence of 24VAC sourced from the "R" terminal. The binary input conditioning circuitry for these inputs is designed to be compatible with conventional wall thermostats. n. Board Level Jumpers: JP1 Senice.Test Mode JP2 Continuous:'cyding fan JP3 Water:'G1yco1 (Loop tluid) JP4 Freeze fault protection JP5 Room Temperature Set point adjustment range JP6 Local control type (thermostat or room sensor) JP: Primary heating source (compressor or other) ]P8 L'4 expansion module (present or not required) 3. Binary Outputs: 9 total (Main Fan, Compressor, Reversing Valve, Isolation valve/Pump Request, 3 Board Status LEDs, Room Sensor Status LED, Thermostat "A" output) Job Number: LL2OFE Page Prepared Date: 10/8/2020 Job Name: Brackets Point House 32 of 35 www.DaikinApplied.com
