inside wall about four feet above floor. Never
install thermostat on an outside wall or where
it will be influenced by drafts, hot or cold water
pipes, lighting fixtures, television, rays of the sun
or near a fireplace. Keep large furniture away from

it is connected. See Figures 27 and 28 for
desired system and heat anticipator setting. If
system tends to overheat above the thermostat's
temperature setting, reduce heat anticipator
setting by .1 or .2 amps. If system tends to short
cycle without reaching desired room temperature,
increase heat anticipator setting by .1 or .2 amps.
