1 Operating Range is the temperature range in which the thermostat will accurately
display temperature.
2 Low Limit Temperature is the temperature setting of an internal, temperature-controlled
mechanical switch in a circuit between RH and W for Models 8344, 8348, 8363 and 8366,
and between R and W2 for Models 8346 and 8365. This device is intended to prevent
freezing of water pipes should battery replacement be neglected.
3 High Limit Temperature is the setting of an internal, temperature-controlled mechanical
switch in the circuit between the RH and the W terminal (W and W2 terminals for Model
8348 and 8366). This device will limit the room temperature should the contacts of the
heat relay remain closed. Applies to Models 8344, 8348, 8363 and 8366 only.
