3. IMPORTANT If your system needs isolating relay and one is not installed no hazard will exist but the system will not operate The thermostat will not be damaged unless you connect it directly to 120 Vac If the current draw of the primary control is below 0 08A a 202394B Resistor should be installed on the furnace terminal strip to increase the current draw of the primary contro to 0 08A or greater This would alleviate any compatibility problem between the T8600 Thermostat and the system due to a low current draw For installation details refer to instructions packed with the resistor The T8601 T8602 and T8603 Thermostats are com patible with other control systems without the need for an isolating relay WHEN INSTALLING THIS PRODUCT 1 Read these instructions carefully Failure to follow them could damage the product or cause a hazardous condition 2 Checkthe ratings given on the product to make sure the product is suitable for your application 3 Installer must be a trained experienced service technician 4 Allow thermostat to warm to room temperature be fore programming 5 After installation is complete check out product operation as provided in these instructions CAUTION Disconnect power supply to prevent electrical shock or equipment damage LOCATION Install thermostat and wallplate about 5 ft 1 5 m above the floor in an area with good air circulation at room temperature Do not i
