Tekmar 352 House Control
One zone, boiler/injection
With outdoor and indoor sensor
Control never used
Details -
The House Control 352 controls the space temperature of one heating zone. The required supply water temperature to the zone is
controlled by operating a boiler.
Piping and Heat Source Details The system consists of three heating units plumbed in series. Either a high, low or a condensing
boiler can be used with this application.
Warm Weather Shut Down (WWSD) When the outdoor temperature rises above the RTU dial setting and the heating zone is satisfied,
the 352 turns off the boiler and the system pump (P1).
Boiler Operation The 352 uses an outdoor reset strategy together with indoor temperature feedback from the RTU to adjust the system
supply water temeprature. In order to maximize boiler efficiency, the 352 operates the boiler at the lowest possible water temperature.
The 352 automatically adjusts the boiler differential to prevent the boiler from short cycling. During low heating loads the 352 turns on
the boiler and ensures at least the minimum boiler water temperature is reached. The system pump (P1) remains on when the control
is not in WWSD.
UnOccupied (Night Setback) The heating zone can be switched into an UnOccupied (Night Setback) mode by closing an external
UnOccupied switch (U1). When the control is switched into UnOccupied mode, the UnOccupied dial is used to set the desired indoor
temperature.

Tekmar 054 Room Thermostat
Never used
Details -
The tekmar Room Temperature Unit (RTU) 054 consists of a temperature sensor and
an adjustable dial which is used to set the desired indoor temperature. The RTU 054 dial
has a temperature range from 40 to 100°F (4 to 38°C). In cases where a restricted
temperature range is required, the dial rotation can be limited using limit pins supplied
with the RTU. A 10K temperature sensor (e.g. 071, 072 etc.) can be mounted remote
from the RTU. This RTU does not work with older tekmar controls. If the RTU is to be
mounted on a 2" x 4" electrical box, an Adaptor Plate 007 is available for use.
