Arduino library to control a pilot wire heatings using a ESP8266 board as the center of the controller.

• drive PW heatings with 4 orders
• set default order
• change order for a period of time defined in seconds, minutes or hours.
• manage events

Define heating with pin D1 and D2 to manage sinusoidal (so order PW heating). Swap order to CONFORT position for 25 minutes.

HeatZ heat;
void setup() {
 heat.begin(D1, D2, ARRET);
 heat.changeOrder(CONFORT, 25, MINUTES);
}
void loop() { // unused }

This following example shows how to use events as onChange. It prints the label order for as long as the order changes.

It is called for the first time the heating is switch to default order.

HeatZ heat;
void callback(HeatZ* h) {
 Serial.print("Heating in mode ");
 Serial.println(h->getOrderLabel());
}
void setup() {
 heat.onChange(callback);
 heat.begin(D1, D2, ARRET);
 heat.changeOrder(CONFORT, 25, MINUTES);
}
void loop() { // unused }

• Order (type hzOrder_t) values: CONFORT, HORSGEL, ARRET and ECO
• Unit of time (type hzPeriod_t) values: HOURS, MINUTES, SECONDS
• One of the pins used by the heating (type hzPin_t): PIN1 or PIN2

The library is initialize with begin() function with one of the following:

HeatZ::begin(uint8_t pin1, uint8_t pin2, hzOrder_t defaultOrder = HORSGEL, String name = "room")

Parameters:

• pin1 is the digital pin to control the positive part of the sinusoidal
• pin2 is the digital pin to control the negative part of the sinusoidal
• defaultOrder (optional) is the order set to the control by default
• name (optional) is the label for this heatings

And swap to a different order given by changeOrder function for a duration.

This function uses Ticker Arduino library.

int changeOrder(hzOrder order, int duration, hzPeriod_t unit); 

Parameters:

• order to swap to
• duration to keep this order on
• unit for the duration

onChange(void (*callback)(HeatZ* heat));
