Stage 1 Heating¤

Operating with a common wire connection:

If installing the thermostat with a common wire connection, place the

ENERGY HARVESTING switch in the OFF position. Upon first power

up or following a power failure the thermostat will run under normal

operating conditions within 5 minutes.

Operating without a common wire connection:

If installing the thermostat without a common wire connection, do the

following:

Prior to mounting the thermostat –

Place the ENERGY HARVESTING switch in the ON position.

Place the HEAT switch in the ON position.

At first power up or following a power failure it may take the thermostat

7 to 20 minutes for the power harvesting circuitry to charge before going

into the first heating call.

An optional method of bypassing the 7 to 20 minute wait is to connect

a 9V battery to the sensor board battery terminals.

LED D1 will light once the battery is connected.

When done charging the LED will become dim or go off (approximately

2 minutes).

Remove battery and the thermostat will run under normal operating

conditions within 5 minutes.

While the battery is attached the unit may be tested as stated below.

NOTE: The thermostat will not attempt to control temperature

until the battery is removed.

IMPORTANT NOTICE TO INSTALLERS

To place thermostat in test mode connect a 9 volt battery to sensor

board battery terminals.

If storage capacitors are not charged the LED will come on in the

upper right corner. If the storage capacitors are charged there will be

no light.

NOTE: To test, plug-in setpoints are required.
