Setup
The TPOne-M can be used as a single channel
programmable thermostat to control the
temperature regulation of the heating system only
or as a two channel programmable thermostat
to control the heating and the time schedule of
a domestic hot water circuit. The domestic hot
water selection will have been chosen in the
startup wizard on initial installation. Choose this
setting after installation to switch the domestic
hot water option on/o.
Default: Set at startup
Note: Settings in the menu which are required for
domestic hot water are only accessable if the Hot
Water Setup is switched on. TPOne-M controls
only the time schedule for domestic hot water and
should always be used with a suitable hot water
cylinder thermostat.
Control Type This allows the thermostat to be set to run in On/
O mode or in chrono-proportional 3, 6 or 12
cycle rate.
Default: Chrono 6
Note: for condensing boiler control tests have
shown that boiler efficiency is significantly
improved when controlled by a chrono-
proportional type controller
