Ventilation management.

Schedule ventilation periods to maintain proper indoor air quality for your tenants when they are present and make sure you are saving energy while they are away. Add a Pelican carbon dioxide (CO2) sensor thermostat and the PEARL automatically adjust ventilation rates based on how occupied the room is, to help save on energy.

Economizer logic.

Modern buildings utilize technology to enhance energy efficiency values. The PEARL economically uses free cold outdoor air to condition your facility. And provides advanced fault detection and diagnostics notifications to prevent the miss use of the outdoors.

Varaible Speed Fan.

Set the correct speed for your supply and exhaust fans to run at during different heating, cooling, and ventilation cycles.

Modulate Heating and Cooling

The PEARL can modulate heating and cooling points to automatically maintain a supply temperature output that matches the room's demand.

| PEARL Inputs and Outputs

MODULATING OUTPUTS

(A1, A2) 0 - 10 VDC Signals

Two modulating outputs that are most commonly used for outside damper, variable speed fan, and/or modulating temperature control.

ENABLE OUTPUT

(E) Terminal

During an economizer or demand ventilation cycle, this outputs 24 VAC to turn on exhaust fans or open dampers.​

ANALOG INPUT

(S1, S2) 0 - 10 VDC Signal

When used as an outside air damper controller, the PEARL accepts a feedback signal to confirm the outside damper is in the correct position.​

EXTERNAL INPUTS

(T1, T2, T3) 10K Type II or Dry-Contact

Pull in up to three external temperatures. Most commonly an HVAC unit's discharge, return, and/or outside air temperatures. Or connect a dry-contact into the PEARL to incorporate a third-party occupancy sensor or equipment alarm.

CONNECTION TO THERMOSTAT

(R, C, D) 3-Wires Only

The PEARL and its Pelican thermostat communicate over a three wire connection.
R: 24 VAC, C: Common, D: Data.

DIGITAL OUTPUT

(Y, Y2, W, W2, G) HVAC Unit Control

Remove the wiring module from of your Pelican thermostat and mount it into the PEARL. The PEARL will enable your HVAC equipment's heating, cooling, and fan stages.
