- Page 35 Mounting Mount the T200 series to a suitable surface. The T200 is shipped with an adapter plate (4-1/4 x 4-3/4 in.) that covers the mounting blemishes of a previous thermostat. New installation will not need the adapter plate. Do not mount on a surface that exceeds 125°F (52°C).
- Page 36 CHECKOUT 1. Verify jumper pin selections. 2. Verify that the T200 is wired correctly to your heating and or cooling loads. 3. Confirm that 75 milliamps are available at all times. To measure the current draw connect an ammeter (set to measure milliamps) in series with the heat or cool output. If power value is below 75 milliamps install a 250 ohm 5 watt resistor in parallel across the switched load.
