Outdoor Air Temperature Offset Adjustment; Keypad Lockout (Programmable Models Only) - Carrier Performance TP-PRH-A Installation Instructions Manual

Option 19 — Dry Contact Configuration (non- - programmable models only)
OF — The dry contact is always de- - energized.
ON — The dry contact will operate as a DH relay. This relay is reverse logic.
When the humidity level is above the dehumidify setpoint, the dry contact D1- - D2
will be opened. When the humidity level is below the dehumidify setpoint, D1- - D2
will be closed. There is a +/- - 2% hysteresis around the dehumidify setpoint to
prevent rapid on/off cycling of the DH output. When configured for
dehumidification, the Rc terminal must be connected to one of the dry contact
terminals. This provides power to energize the dehumidify terminal on the cooling
equipment when the dry contact is closed. See Wiring Diagrams for more
information.
Default is OF (off).
Option 20 — Outdoor Air Temperature Offset Adjustment
This selection allows the calibration, or deliberate miscalibration of the outdoor air
temperature sensor reading. The selection ranges from - - 5 to +5_.
Default is 0.
Option 21 — Keypad Lockout (programmable models only)
This selection allows the installer to limit access to the keypad. Selections are OF
(off), 1, 2, 3. These options are independent of Option 24, which allows the
programmable model to be configured as a non- - programmable thermostat.
OF (off) — The user has full access to the keypad.
1 — The user has access to change the setpoints, time of day and calendar.
