This primary relay can be connected to a ptd102 delay in order to put off the power to the spdt relay, this final realy is the only on the way to manipulate the electricity to the motor based totally on y2 terminal from nest thermostat. The thermostat will ship energy to y1 best for 1st velocity and in case it desires extra cooling strength it will start sending power to y1 and y2 at the same time causing the spdt relay to switch strength to high through terminal 3 as the following diagram indicates:.
