T200 Series Erie™ Digital, On/Off Thermostat T200 Serie T200 series thermostats provide temperature control on a variety of heating, cooling and single stage heat pump applications. The large LCD window displays room temperature including 1/5th of a degree increments indicated by a series of up to 5 dashes. The system heat output cycles on a 1 or 2F degree field selectable differential. The cool output differential is fixed at 2F degrees. The setpoint is displayed and changed by pressing one of the setpoint buttons up or down. Installation is simplified by having all of the field wires mounted to the separate wall plate. Features: • LCD window display, qF standard, qC configurable. • Jumper selectable 5 minute time delay for heating and cooling application. • Mechanical contact for low limit protection (optional). • Base adaptor plate standard.
