Jumpers are electronic components that are used to short two points to achieve a certain operation.
Below is an illustration of what is a jumper and how it is used.
The HyperStat hardware of Carrier uses several jumpers for various purposes. These jumpers and their operation vary in the case of the HyperStat Conventional and the HyperStat P1P2 variant.
| HyperStat Conventional
The HyperStat conventional variant uses jumpers in 4 different locations to achieve different types of operations
#1:
At this position, a jumper is used to short the RH and RC to enable and power both the cooling and heating stage relays for use.
When the jumper is not used, only three of the relays for the heating stages are enabled with the power supplied, and the cooling stage relays are disabled.
#2:
In this position,
Short if the HyperStat conventional device is the last device on the RS485 line.
If it is not shorted, there is no terminal resistance, and the device can be used as one of the multi-drop connections.
And another jumper is used for power Isolation, If you do not want to share the power between the connectors of the RS485 bus then this jumper can be used.
#3:
At position 3 three jumpers are used to switch between the voltage and current types of output, 0-10V or 0-20mA.
The pin for the voltage 0-10 V DC denoted by 'V' is shorted with the pin in the center to switch for voltage output.
The pin for the current 4-20 mA out is denoted by 'I' and is shorted with the pin in the center to switch for current output.
It should be noted that by default, the jumper is kept selecting 0-10 VDC output for reference.
#4:
At this position, 2 Jumpers are used to switch between the Digital and Analogs types of inputs.
It should be noted that shorting this jumper position for either A1 or A2 makes the HyperStat ready to receive external digital input through AIn1 and AIn2 terminal connectors. Open the jumpers if analog voltage inputs are to be sensed through Ain1 and Ain2 terminals.
|HyperStat P1P2
The HyperStat P1P2 variant uses jumpers in 3 different locations to achieve different types of operations.
#1:
At this position, one of the jumpers is used for ground selection to select between the P1P2 Gnd external supply’s ground. The other second jumper is the power selection jumper which selects between P1P2 Gnd and 24V external supply’s ground
And when the pin for the 24V input is shorted with the pin in the center the 24V AC or DC common supply is selected or enabled.
The second jumper in this position is used as a power jumper to switch between the P1P2 power line and the 24 Volt common supply.
When the pin for the P1P2 16V power line is shorted with the pin in the center, the P1P2 16V power line is selected or enabled.
And when the pin for the 24V input is shorted with the pin in the center, the 24V AC or DC common supply is selected or enabled.
At all times both the jumpers are either connected to pins P1P2 ground and P1P2 16V power with the pin in the center, or the 24V inputs and pins in the center.
And jumpers cannot be used for two different pin combinations as below.
#2:
At this position, 2 Jumpers are used to switch between the Digital and Analogs types of inputs.
It should be noted that shorting this jumper position for either A1 or A2 makes the HyperStat ready to receive external digital input through AIn1 and AIn2 terminal connectors. Open the jumpers if analog voltage inputs are to be sensed through Ain1 and Ain2 terminals.
The switch in this case can be a door or window switch.
#3:
At this position, 3 jumpers are used to switch between the voltage and current types of output, 0-10V or 0-20mA.
The pin for the voltage 0-10VDC is denoted by 'V' and is shorted with the pin in the center to switch for voltage output.
The pin for the current 4-20 mA out is denoted by 'I' and is shorted with the pin in the center to switch for current output.
It should be noted that by default, the jumper is kept selecting 0-10 VDC output for reference.
At this position, a 3 third jumper is used to switch between the type of power that powers the analog output circuit.
The pin for the P1P2 16V is shorted with the pin in the center, to enable the P1P2 16V to power the analog output circuit.
And the pin for VDD 16V is shorted with the pin in the center, to enable VDD16V to power the analog output circuit.
Below is an illustration of the possible jumper location for all the analog outputs.
