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 to the
right.
NOTE:
The thermostat will not attempt to control temperature
until the battery is removed.
IMPORTANT NOTICE TO INSTALLERS TESTING:
To place thermostat in test mode insert 9 volt battery into sensor
board battery terminals.
If storage capacitors are not charged a light will come on in the upper
right corner.
NOTE: To test, plug-in setpoints are required.
Prior to the test verify that your SW5 switch settings are set correctly
per your application.
Heating:
H1 setpoint must be installed.
ECONOMY switch must be in the OFF position.
1. Press the “C” button.
Heat (W1) will turn on.
2. Slide the ECONOMY switch to the ON position.
If H2 setpoint is installed, heat (W1) will remain on.
If H2 setpoint is not installed, heat (W1) will turn off.
3. Press the “C” button again.
All outputs will turn off and heating test is complete.
Remove battery to end testing.
