15. INSTALL A ROOM THERMOSTAT on an 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 thermostat so there
will be free movement of room air around this control.
Heat Anticipator in Thermostat should be set to match the
requirements of the control to which it is connected. See Table
4. 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.

16. INSTALL ELECTRIC WIRING in accordance with
National Electric Code or the Canadian Electrical Code and
local regulations. See Figures 11 through 14 for applicable
wiring diagram. A separate Electrical Circuit should be run
from meter with a Fused Disconnect Switch in this Circuit.
When installed, the boiler must be electrically grounded in
accordance with local codes or, in the absence of local
codes, with the National Electrical Code, ANSI/NFPA 70,
and/or the CSA C22.1 Electrical Code, if an external electrical
source is utilized.
For zone valve wiring, a separate 24V transformer is
required rather than attempting to use the boiler mounted
control. Consult zone valve manufacturer for assistance.

If system tends to overheat above thermostat's temperature setting, reduce heat anticipator setting by 0.1
or 0.2 amps. If system tends to shortcycle without reaching desired room temperature, increase heat
anticipator setting by 0.1 or 0.2 amps.
